SDL_PushGPUFragmentUniformData - Man Page

Defined in SDL3/SDL_gpu.h

#include "SDL3/SDL.h"

void SDL_PushGPUFragmentUniformData(
    SDL_GPUCommandBuffer *command_buffer,
    Uint32 slot_index,
    const void *data,
    Uint32 length);

Subsequent draw calls will use this uniform data.

The data being pushed must respect std140 layout conventions. In practical terms this means you must ensure that vec3 and vec4 fields are 16-byte aligned.

command_buffer

a command buffer.

slot_index

the fragment uniform slot to push data to.

data

client data to write.

length

the length of the data to write.

This function is available since SDL 3.2.0.
