sdlGetGpuDriver function

String? sdlGetGpuDriver(
  1. int index
)

Get the name of a built in GPU driver.

The GPU drivers are presented in the order in which they are normally checked during initialization.

The names of drivers are all simple, low-ASCII identifiers, like "vulkan", "metal" or "direct3d12". These never have Unicode characters, and are not meant to be proper names.

\param index the index of a GPU driver. \returns the name of the GPU driver with the given index.

\since This function is available since SDL 3.1.3.
