NAME¶

SDL_stack_free - Free memory previously allocated with SDL_stack_alloc.

SYNOPSIS¶

#include <SDL3/SDL_stdinc.h>

#define SDL_stack_free(data) ((void)(data))

DESCRIPTION¶

If SDL used alloca() to allocate this memory, this macro does nothing (other than insert ((void)(data) so the compiler sees an expression) and the allocated memory will be automatically released when the function that called SDL_stack_alloc() returns. If SDL used SDL_malloc(), it will SDL_free the memory immediately.

MACRO PARAMETERS¶

data

the pointer, from SDL_stack_alloc(), to free.

THREAD SAFETY¶

It is safe to call this macro from any thread.

AVAILABILITY¶

This macro is available since SDL 3.2.0.
