SIGRELSE(3) Library Functions Manual SIGRELSE(3)

sigrelse — manipulate current signal mask

Standard C Library (libc, -lc)

#include <signal.h>

int
sigrelse(int sig);

This interface is made obsolete by sigprocmask(2).

The () function removes the signal sig from the calling process' signal mask.

If successful, the sigrelse() function returns 0. Otherwise -1 is returned and errno is set to indicate the error.

The sigrelse() function will fail if:

[]
The argument sig is not a valid signal number.

sigprocmask(2), sighold(3)

The sigrelse() function conforms to IEEE Std 1003.1-2001 (“POSIX.1”). It was however marked as obsolete in the IEEE Std 1003.1-2008 (“POSIX.1”) revision of the standard.
