NAME

       SDL_realloc - Change the size of allocated memory.

HEADER FILE

       Defined in SDL3/SDL_stdinc.h

SYNOPSIS

       #include "SDL3/SDL.h"

       void * SDL_realloc(void *mem, size_t size);

DESCRIPTION

       The memory returned by this function must be freed with

       SDL_free ().

       If size is 0, it will be set to 1. Note that this is unlike some other C runtime realloc implementations,
       which may treat realloc(mem,0) the same way as free(mem) .

       If mem is NULL, the behavior of this function is equivalent to

       SDL_malloc (). Otherwise, the function can have one of three possible outcomes:

       • If it returns the same pointer as mem , it means that mem was resized
         in place without freeing.

       • If it returns a different non-NULL pointer, it means that mem was freed
         and cannot be dereferenced anymore.

       • If it returns NULL (indicating failure), then mem will remain valid and
         must still be freed with SDL_free ().

FUNCTION PARAMETERS

       mem    a pointer to allocated memory to reallocate, or NULL.

       size   the new size of the memory.

RETURN VALUE

       Returns a pointer to the newly allocated memory, or NULL if allocation failed.

THREAD SAFETY

       It is safe to call this function from any thread.

AVAILABILITY

       This function is available since SDL 3.2.0.
