SIGINTERRUPT(3)		   Linux Programmer's Manual	       SIGINTERRUPT(3)

NAME
       siginterrupt - allow signals to interrupt system	calls

SYNOPSIS
       #include	<signal.h>

       int siginterrupt(int sig, int flag);

DESCRIPTION
       The siginterrupt() function changes the restart behaviour when a	system
       call is interrupted by the signal sig.  If the flag argument  is	 false
       (0),  then  system calls	will be	restarted if interrupted by the	speci-
       fied signal sig.	 This is the default  behaviour	 in  Linux.   However,
       when a new signal handler is specified with the signal(2) function, the
       system call is interrupted by default.

       If the flags argument is	true (1) and no	 data  has  been  transferred,
       then a system call interrupted by the signal sig	will return -1 and the
       global variable errno will be set to EINTR.

       If the flags argument is	true (1) and data transfer has	started,  then
       the  system  call will be interrupted and will return the actual	amount
       of data transferred.

RETURN VALUE
       The siginterrupt() function returns 0 on	success, or -1 if  the	signal
       number sig is invalid.

ERRORS
       EINVAL The specified signal number is invalid.

CONFORMING TO
       BSD 4.3
