// API version changelog:
//
// 1.0.0 - initial release
// 1.0.1 - Bugfix: IsFrameCapturing() was returning false for captures that were triggered
//         by keypress or TriggerCapture, instead of Start/EndFrameCapture.
// 1.0.2 - Refactor: Renamed eRENDERDOC_Option_DebugDeviceMode to eRENDERDOC_Option_APIValidation
// 1.1.0 - Add feature: TriggerMultiFrameCapture(). Backwards compatible with 1.0.x since the new
//         function pointer is added to the end of the struct, the original layout is identical
// 1.1.1 - Refactor: Renamed remote access to target control (to better disambiguate from remote
//         replay/remote server concept in replay UI)
// 1.1.2 - Refactor: Renamed "log file" in function names to just capture, to clarify that these
//         are captures and not debug logging files. This is the first API version in the v1.0
//         branch.
// 1.2.0 - Added feature: SetCaptureFileComments() to add comments to a capture file that will be
//         displayed in the UI program on load.
// 1.3.0 - Added feature: New capture option eRENDERDOC_Option_AllowUnsupportedVendorExtensions
//         which allows users to opt-in to allowing unsupported vendor extensions to function.
//         Should be used at the user's own risk.
//         Refactor: Renamed eRENDERDOC_Option_VerifyMapWrites to
//         eRENDERDOC_Option_VerifyBufferAccess, which now also controls initialisation to
//         0xdddddddd of uninitialised buffer contents.
// 1.4.0 - Added feature: DiscardFrameCapture() to discard a frame capture in progress and stop
//         capturing without saving anything to disk.
// 1.4.1 - Refactor: Renamed Shutdown to RemoveHooks to better clarify what is happening
// 1.4.2 - Refactor: Renamed 'draws' to 'actions' in callstack capture option.
// 1.5.0 - Added feature: ShowReplayUI() to request that the replay UI show itself if connected
// 1.6.0 - Added feature: SetCaptureTitle() which can be used to set a title for a
//         capture made with StartFrameCapture() or EndFrameCapture()

// RenderDoc API entry point

//
// The name is the same as the typedef - "RENDERDOC_GetAPI"
//
// This function is not thread safe, and should not be called on multiple threads at once.
// Ideally, call this once as early as possible in your application's startup, before doing
// any API work, since some configuration functionality etc has to be done also before
// initialising any APIs.
//
// Parameters:
//   version is a single value from the RENDERDOC_Version above.
//
//   outAPIPointers will be filled out with a pointer to the corresponding struct of function
//   pointers.
//
// Returns:
//   1 - if the outAPIPointers has been filled with a pointer to the API struct requested
//   0 - if the requested version is not supported or the arguments are invalid.
