_c_exit

Perform _exit cleanup without terminating the program.

Defined in header <process.h>

Syntax

#include <process.h>
void _c_exit(void);

Portability

Remarks

_c_exit performs the same cleanup as _exit, except that it does not terminate the calling process. Interrupt vectors altered by the startup code are restored; no other cleanup is performed.

Return value

None.
