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

       siginterrupt - allow signals to interrupt system calls

       #include <signal.h>

       int siginterrupt(int sig, int flag);

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

	   _BSD_SOURCE || _XOPEN_SOURCE >= 500 ||
	   || /* Since glibc 2.12: */ _POSIX_C_SOURCE >= 200809L

       The siginterrupt() function changes the restart behavior 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	speciā€
       fied signal sig.	 This is the default behavior in Linux.

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

       If  the	flag  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.

       The siginterrupt() function returns 0 on success.  It returns -1 if the
       signal number sig is invalid, with errno set to indicate the  cause  of
       the error.

       EINVAL The specified signal number is invalid.

       4.3BSD,	POSIX.1-2001.	POSIX.1-2008 marks siginterrupt() as obsolete,
       recommending the use of sigaction(2) with the SA_RESTART flag instead.
