                    | Defined in header  <stdlib.h> | ||
| int at_quick_exit( void (*func)() ); | (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 shall support the registration of at least 32 functions.

[edit] Parameters
| func | - | pointer to a function to be called on normal program termination | 
[edit] Return value
0 if the registration succeeds, nonzero value otherwise.
[edit] Example
Run this code
#include <stdlib.h> #include <stdio.h> void f1() { puts("pushed first"); fflush(stdout); } void f2() { puts("pushed second"); } int main(void) { at_quick_exit(f1); at_quick_exit(f2); quick_exit(0); }
Output:
pushed second pushed first
