Reference for RenderDoc in-application API
|
|
|
|
|
|
This page describes the RenderDoc API exposed to applications being captured, both in overall organisation as well as a specific reference on each function.
|
|
|
|
.. cpp:function:: void GetAPIVersion(int *major, int *minor, int *patch)
|
|
|
|
|
|
This function returns the actual API version of the implementation returned. Version numbers follow `semantic versioning <http://semver.org/>`_ which means the implementation returned may have a higher minor and/or patch version than requested: New patch versions are identical and backwards compatible in functionality. New minor versions add new functionality in a backwards compatible way.
|
|
|
|
:param int* major: will be filled with the major version of the implementation's version.
|
|
:param int* minor: will be filled with the minor version of the implementation's version.
|
|
:param int* patch: which will be filled with the patch version of the implementation's version.
|
|
:return: None
|
|
|
|
|
|
.. cpp:function:: void SetCaptureOptionU32(RENDERDOC_CaptureOption opt, uint32_t val)
|
|
|
|
Set one of the options for tweaking some behaviours of capturing. Note that each option only takes effect from after it is set - so it is advised to set these options as early as possible, ideally before any graphics API has been initialised.
|
|
|
|
:param RENDERDOC_CaptureOption opt: specifies which capture option should be set.
|
|
:param uint32_t val: the unsigned integer value to set for the above option.
|
|
:return: The function returns 1 if the option is valid, and the value set on the option is within valid ranges. The function returns 0 if the option is not a :cpp:enum:`RENDERDOC_CaptureOption` enum, or the value is not valid for the option.
|
|
|
|
.. cpp:function:: void SetCaptureOptionF32(RENDERDOC_CaptureOption opt, float val)
|
|
|
|
Set one of the options for tweaking some behaviours of capturing. Note that each option only takes effect from after it is set - so it is advised to set these options as early as possible, ideally before any graphics API has been initialised..
|
|
|
|
:param RENDERDOC_CaptureOption opt: specifies which capture option should be set.
|
|
:param float val: the floating point value to set for the above option.
|
|
:return: The function returns 1 if the option is valid, and the value set on the option is within valid ranges. The function returns 0 if the option is not a :cpp:enum:`RENDERDOC_CaptureOption` enum, or the value is not valid for the option.

|
|
|
|
specifies whether all command lists should be captured on APIs where multithreaded submission is not optimal such as D3D11, rather than only capturing those submitted during the frame. Default is off.

|
|
|
|
.. cpp:enumerator:: RENDERDOC_OverlayBits::eRENDERDOC_Overlay_All

is equal to `~0U` so all bits are enabled.
|
|
|
|
.. cpp:enumerator:: RENDERDOC_OverlayBits::eRENDERDOC_Overlay_None

|
|
|
|
.. cpp:function:: void MaskOverlayBits(uint32_t And, uint32_t Or)

|
:param uint32_t And: is a 32-bit value the mask is binary-AND'd with before processing ``Or``.
|
|
:param uint32_t Or: is a 32-bit value the mask is binary-OR'd with after processing ``And``.
|
|
|
|
.. cpp:function:: void Shutdown()
|
|
|
|
This function will attempt to shut down and remove RenderDoc and its hooks from the target process. It must be called as early as possible in the process, and will have undefined results if any graphics API functions have been called.
|
|
|
|
.. cpp:function:: void UnloadCrashHandler()
|
|
|
|
This function will remove RenderDoc's crash handler from the target process. If you have your own crash handler that you want to handle any exceptions, RenderDoc's handler could interfere so it can be disabled.
|
|
|
|
.. cpp:function:: void SetLogFilePathTemplate(const char *pathtemplate)
|
|
|
|
Set the template for new captures. The template can either be a relative or absolute path, which determines where captures will be saved and how they will be named. If the path template is ``my_captures/example`` then captures saved will be e.g. ``my_captures/example_frame123.rdc`` and ``my_captures/example_frame456.rdc``. Relative paths will be saved relative to the process's current working directory. The default template is in a folder controlled by the UI - initially the system temporary folder, and the filename is the executable's filename.
|
|
|
|
:param const char* pathtemplate: specifies the capture path template to set, as UTF-8 null-terminated string.
|
|
|
|
.. cpp:function:: const char *GetLogFilePathTemplate()
|
|
|
|
Get the current log file path template.
|
|
|
|
:return: the current capture path template as a UTF-8 null-terminated string.
|
|
|
|
.. cpp:function:: uint32_t GetNumCaptures()
|
|
|
|
This function returns the number of frame captures that have been made.
|
|
:return: Returns the number of frame captures that have been made
|
|
|
|
.. cpp:function:: uint32_t GetCapture(uint32_t idx, char *logfile, uint32_t *pathlength, uint64_t *timestamp)
|
|
|
|
This function returns the details of a particular frame capture, as specified by an index from 0 to :cpp:func:`GetNumCaptures` - 1.
|
|
|
|
:param uint32_t idx: specifies which capture to return the details of. Must be less than the return value of:cpp:func:`GetNumCaptures`.
|
|
:param char* logfile: is an optional parameter filled with the UTF-8 null-terminated path to the file. There must be enough space in the array to contain all characters including the null terminator. If set to NULL, nothing is written.
|
|
:param uint32_t* pathlength: is an optional parameter filled with the byte length of the above `logfile` including the null-terminator. If set to NULL, nothing is written.
|
|
:param uint64_t* timestamp: is an optional parameter filled with the 64-bit timestamp of the file - equivalent to the `time()` system call. If set to NULL, nothing is written.
|
|
:return: Returns ``1`` if the capture index was valid, or ``0`` if it was out of range.
|
|
|
|
.. note::
|
|
|
|
It is advised to call this function twice - first to obtain ``pathlength`` so that sufficient space can be allocated. Then again to actually retrieve the path.
|
|
|
|
|
|
The path follows the template set in :cpp:func:`SetLogFilePathTemplate` so it may not be an absolute path.
|
|
|
|
.. cpp:function:: void TriggerCapture()
|
|
|
|
This function will trigger a capture as if the user had pressed one of the capture hotkeys. The capture will be taken from the next frame presented to whichever window is considered current.
|
|
|
|
.. cpp:function:: uint32_t IsRemoteAccessConnected()
|
|
|
|
This function returns a value to indicate whether the RenderDoc UI is currently connected to the current process.
|
|
|
|
:return: Returns ``1`` if the RenderDoc UI is currently connected, or ``0`` otherwise.
|
|
|
|
.. cpp:function:: uint32_t LaunchReplayUI(uint32_t connectRemoteAccess, const char *cmdline)
|
|
|
|
This function will determine the closest matching replay UI executable for the current RenderDoc module and launch it.
|
|
|
|
:param uint32_t connectRemoteAccess: should be set to 1 if the UI should immediately connect to the application.
|
|
:param const char* cmdline: is an optional UTF-8 null-terminated string to be appended to the command line, e.g. a capture filename. If this parameter is NULL, the command line will be unmodified.
|
|
:return: If the UI was successfully launched, this function will return the PID of the new process. Otherwise it will return ``0``.
|
|
|
|
.. cpp:function:: void SetActiveWindow(RENDERDOC_DevicePointer device, RENDERDOC_WindowHandle wndHandle)
|
|
|
|
This function will explicitly set which window is considered active. The active window is the one that will be captured when the keybind to trigger a capture is pressed.
|
|
|
|
:param RENDERDOC_DevicePointer device: is a handle to the API 'device' object that will be set active. Must be valid.
|
|
:param RENDERDOC_WindowHandle wndHandle: is a handle to the platform window handle that will be set active. Must be valid.
|
|
|
|
.. note::
|
|
|
|
``RENDERDOC_DevicePointer`` is a typedef to ``void *``. The contents of it are API specific:
|
|
|
|
* For D3D11 it must be the ``ID3D11Device`` device object.
|
|
* For OpenGL it must be the ``HGLRC`` or ``GLXContext`` context object.
|
|
* For Vulkan it must be the dispatch table pointer within the ``VkInstance``. This is a pointer-sized value at the location pointed to by the ``VkInstance``. NOTE - this is not the actual ``VkInstance`` pointer itself.
|
|
|
|
``RENDERDOC_WindowHandle`` is a typedef to ``void *``. It is the platform specific ``HWND``, ``xcb_window_t``, or Xlib ``Window``.
|
|
|
|
.. cpp:function:: void StartFrameCapture(RENDERDOC_DevicePointer device, RENDERDOC_WindowHandle wndHandle)
|
|
|
|
This function will immediately begin a capture for the specified device/window combination.
|
|
|
|
:param RENDERDOC_DevicePointer device: is a handle to the API 'device' object that will be set active. May be NULL to wildcard match.
|
|
:param RENDERDOC_WindowHandle wndHandle: is a handle to the platform window handle that will be set active. May be NULL to wildcard match.
|
|
|
|
.. note::
|
|
|
|
``RENDERDOC_DevicePointer`` and ``RENDERDOC_WindowHandle`` are described above in :cpp:func:`SetActiveWindow`.
|
|
``device`` and ``wndHandle`` can either or both be set to NULL to wildcard match against active device/window combinations. This wildcard matching can be used if the handle is difficult to obtain where frame captures are triggered.
|
|
|
|
For example if ``device`` is NULL but ``wndHandle`` is set, RenderDoc will begin a capture on the first API it finds that is active on that window.
|
|
|
|
If the wildcard match has multiple possible candidates, it is not defined which will be chosen. Wildcard matching should only be used when e.g. it is known that only one API is active on a window, or there is only one window active for a given API.
|
|
|
|
If no window has been created and all rendering is off-screen, NULL can be specified for the window handle and the device object can be passed to select that API. If both are set to NULL, RenderDoc will simply choose one at random so is only recommended for the case where only one is present.
|
|
|
|
.. cpp:function:: uint32_t IsFrameCapturing()
|
|
|
|
This function returns a value to indicate whether the current frame is capturing.
|
|
|
|
:return: Returns ``1`` if the frame is currently capturing, or ``0`` otherwise.
|
|
|
|
.. cpp:function:: void EndFrameCapture(RENDERDOC_DevicePointer device, RENDERDOC_WindowHandle wndHandle)
|
|
|
|
This function will immediately end an active capture for the specified device/window combination.
|
|
|
|
:param RENDERDOC_DevicePointer device: is a handle to the API 'device' object that will be set active. May be NULL to wildcard match.
|
|
:param RENDERDOC_WindowHandle wndHandle: is a handle to the platform window handle that will be set active. May be NULL to wildcard match.
|
|
|
|
.. note::
|
|
|
|
``RENDERDOC_DevicePointer`` and ``RENDERDOC_WindowHandle`` are described above in :cpp:func:`SetActiveWindow`.
|
|
``device`` and ``wndHandle`` can either or both be set to NULL to wildcard match against active device/window combinations. This wildcard matching can be used if the handle is difficult to obtain where frame captures are triggered.
|
|
|
|
Wildcard matching of `device` and `wndHandle` is described above in :cpp:func:`BeginFrameCapture`.
|
|
|
|
There will be undefined results if there is not an active frame capture for the device/window combination.
