quick_exit

Defined in header <stdlib.h> 
_Noreturn void quick_exit( int exit_code );
 +(since C11)
(until C23) +		 
[[noreturn]] void quick_exit( int exit_code );
+		 (since C23)

Causes normal program termination to occur without completely cleaning the resources.

+

Functions passed to at_quick_exit are called in reverse order of their registration. After calling the registered functions, calls _Exit(exit_code).

+

Functions passed to atexit or signal handlers passed to signal are not called.

+

Parameters

+ +
exit_code - exit status of the program

Return value

(none)

+

Example

#include <stdlib.h>
+#include <stdio.h>
+ 
+void f1(void)
+{
+    puts("pushed first");
+    fflush(stdout);
+}
+ 
+void f2(void)
+{
+    puts("pushed second");
+}
+ 
+void f3(void)
+{
+    puts("won't be called");
+}
+ 
+int main(void)
+{
+    at_quick_exit(f1);
+    at_quick_exit(f2);
+    atexit(f3);
+    quick_exit(0);
+}

Output:

+
pushed second
+pushed first
