POSIX_SPAWNATTR_GETSI... BSD Library Functions Manual POSIX_SPAWNATTR_GETSI...

NAME
     posix_spawnattr_getsigmask, posix_spawnattr_setsigmask — get and set the
     spawn-sigmask attribute of a spawn attributes object

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <spawn.h>

     int
     posix_spawnattr_getsigmask(const posix_spawnattr_t *restrict attr,
	 sigset_t *restrict sigmask);

     int
     posix_spawnattr_setsigmask(posix_spawnattr_t *attr,
	 const sigset_t *restrict sigmask);

DESCRIPTION
     The posix_spawnattr_getsigmask() function obtains the value of the spawn-
     sigmask attribute from the attributes object referenced by attr.

     The posix_spawnattr_setsigmask() function sets the spawn-sigmask
     attribute in an initialized attributes object referenced by attr.

     The spawn-sigmask attribute represents the signal mask in effect in the
     new process image of a spawn operation (if POSIX_SPAWN_SETSIGMASK is set
     in the spawn-flags attribute).  The default value of this attribute is
     unspecified.

RETURN VALUES
     The posix_spawnattr_getsigmask() and posix_spawnattr_setsigmask() func‐
     tions return zero.

     tions conform to IEEE Std 1003.1-2001 (“POSIX.1”).
