SDL_memset4 - Man Page

#include <SDL3/SDL_stdinc.h>

void * SDL_memset4(void *dst, Uint32 val, size_t dwords);

This function will set a buffer of dwords Uint32 values, pointed to by dst, to the value specified in val.

Unlike SDL_memset, this sets 32-bit values, not bytes, so it's not limited to a range of 0-255.

dst

the destination memory region. Must not be NULL.

val

the Uint32 value to set.

dwords

the number of Uint32 values to set in dst.

Returns dst.

It is safe to call this function from any thread.

This function is available since SDL 3.2.0.
