sdlCreateGpuBuffer function gpu

Pointer<SdlGpuBuffer> sdlCreateGpuBuffer(Pointer<SdlGpuDevice> device, Pointer<SdlGpuBufferCreateInfo> createinfo)

Creates a buffer object to be used in graphics or compute workflows.

The contents of this buffer are undefined until data is written to the buffer.

Note that certain combinations of usage flags are invalid. For example, a buffer cannot have both the VERTEX and INDEX flags.

If you use a STORAGE flag, the data in the buffer must respect std140 layout conventions. In practical terms this means you must ensure that vec3 and vec4 fields are 16-byte aligned.

There are optional properties that can be provided through props. These are the supported properties:

• SDL_PROP_GPU_BUFFER_CREATE_NAME_STRING: a name that can be displayed in debugging tools.

\param device a GPU Context. \param createinfo a struct describing the state of the buffer to create. \returns a buffer object on success, or NULL on failure; call SDL_GetError() for more information.

\since This function is available since SDL 3.2.0.
