at_quick_exit

Defined in header <stdlib.h> 
int at_quick_exit( void (*func)(void) );
-		 (since C11)

Registers the function pointed to by func to be called on quick program termination (via quick_exit).

-

Calling the function from several threads does not induce a data race. The implementation is guaranteed to support the registration of at least 32 functions. The exact limit is implementation-defined.

-

The registered functions will not be called on normal program termination. If a function need to be called in that case, atexit must be used.

-

Parameters

- -
func - pointer to a function to be called on quick program termination

Return value

​0​ if the registration succeeds, nonzero value otherwise.

-

Example

#include <stdlib.h>
-#include <stdio.h>
- 
-void f1(void)
-{
-    puts("pushed first");
-    fflush(stdout);
-}
- 
-void f2(void)
-{
-    puts("pushed second");
-}
- 
-int main(void)
-{
-    at_quick_exit(f1);
-    at_quick_exit(f2);
-    quick_exit(0);
-}

Output:

-
pushed second
-pushed first
