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(). ATTRIBUTES

PROLOG
This manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the correspond- ing Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux. NAME
siginterrupt -- allow signals to interrupt functions SYNOPSIS
#include <signal.h> int siginterrupt(int sig, int flag); DESCRIPTION
The siginterrupt() function shall change the restart behavior when a function is interrupted by the specified signal. The function sigin- terrupt(sig, flag) has an effect as if implemented as: int 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 VALUE
Upon successful completion, siginterrupt() shall return 0; otherwise, -1 shall be returned and errno set to indicate the error. ERRORS
The siginterrupt() function shall fail if: EINVAL The sig argument is not a valid signal number. The following sections are informative. EXAMPLES
None. APPLICATION USAGE
The siginterrupt() function supports programs written to historical system interfaces. Applications should use the sigaction() with the SA_RESTART flag instead of the obsolescent siginterrupt() function. RATIONALE
None. FUTURE DIRECTIONS
None. SEE ALSO
