Causes normal program termination to occur without completely cleaning the resources.
Destructors of variables with automatic, thread local and static storage durations are not called. Functions passed to at_quick_exit() or atexit() are not called. Whether open resources such as files are closed is implementation defined. If exit_code is EXIT_FAILURE, an implementation-defined status, indicating unsuccessful termination, is returned. In other cases implementation-defined status value is returned.
Parameters
| exit_code | - | exit status of the program |
Return value
(none).
Example
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 | #include <stdlib.h>#include <stdio.h> /* _Exit does not call functions registered with atexit. */void f1(){ puts("pushed first");} void f2(){ puts("pushed second");} int main(void){ printf("Enter main()\n"); atexit(f1); atexit(f2); fflush(stdout); /* _Exit does not flush unwritten buffered data */ _Exit(0);} |
Output:
1 | Enter main() |
