sdlShaderCrossReflectGraphicsSpirv function shadercross

Pointer<SdlShaderCrossGraphicsShaderMetadata> sdlShaderCrossReflectGraphicsSpirv(Pointer<Uint8> bytecode, int bytecodeSize, int props)

Reflect graphics shader info from SPIRV code. If your shader source is HLSL, you should obtain SPIR-V bytecode from SDL_ShaderCross_CompileSPIRVFromHLSL(). This must be freed with SDL_free() when you are done with the metadata.

\param bytecode the SPIRV bytecode. \param bytecode_size the length of the SPIRV bytecode. \param props a properties object filled in with extra shader metadata, provided by the user. \returns A metadata struct on success, NULL otherwise. The struct must be free'd when it is no longer needed.

\threadsafety It is safe to call this function from any thread.
