SDL_memcmp

#include <SDL3/SDL_stdinc.h>

int SDL_memcmp(const void *s1, const void *s2, size_t len);

s1

the first buffer to compare. NULL is not permitted!

s2

the second buffer to compare. NULL is not permitted!

len

the number of bytes to compare between the buffers.

Returns less than zero if s1 is "less than" s2, greater than zero if s1 is "greater than" s2, and zero if the buffers match exactly for len bytes.

It is safe to call this function from any thread.

This function is available since SDL 3.2.0.
