NAME
siginterrupt - allow signals to interrupt functions
SYNOPSIS
#include <signal.h> int siginterrupt(int sig, int flag);
DESCRIPTION
The siginterrupt() function changes the restart behavior when a function is interrupted by the specified signal. The function siginter- rupt(sig, flag) has an effect as if implemented as: siginterrupt(int sig, int flag) { int ret; struct sigaction act; (void) sigaction(sig, NULL, &act); if (flag) act.sa_flags &= SA_RESTART; else act.sa_flags |= SA_RESTART; ret = sigaction(sig, &act, NULL); return ret; }
RETURN VALUES
Upon successful completion, siginterrupt() returns 0. Otherwise, -1 is returned and errno is set to indicate the error.
ERRORS
The siginterrupt() function will fail if: EINVAL The sig argument is not a valid signal number.
USAGE
The siginterrupt() function supports programs written to historical system interfaces. A standard-conforming application, when being writ- ten or rewritten, should use sigaction(2) with the SA_RESTART flag instead of siginterrupt().
