POSIX_SPAWNATTR_SETSIGMASK(3)				   BSD Library Functions Manual 			     POSIX_SPAWNATTR_SETSIGMASK(3)

NAME

     posix_spawnattr_setsigmask posix_spawnattr_getsigmask -- set or get the spawn-sigmask attribute on a posix_spawnattr_t

SYNOPSIS

     #include <spawn.h>

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

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

DESCRIPTION

     The posix_spawnattr_setsigmask() function sets the sigmask on the attributes object referenced by attr.

     The posix_spawnattr_getsigmask() function retrieves the sigmask on the attributes object referenced by attr.

     The argument sigmask is the initial signal mask to be set for the new process on creation if the POSIX_SPAWN_SETSIGMASK flag is set in the
     posix_spawnattr_t.  It's default value must be set via a call to posix_spawnattr_setflags(3) or the behaviour is undefined.

RETURN VALUES

     On success, these functions return 0; on failure they return an error number from <errno.h>.  Additionally, if successful,
     posix_spawnattr_getsigmask() will modify the contents of the sigmask parameter with the current attribute value.

ERRORS

     These functions may fail if:

     [EINVAL]		The value specified by attr is invalid.

     [EINVAL]		The value of attr is invalid.

NAME

       posix_spawnattr_getsigmask, posix_spawnattr_setsigmask - get and set spawn-sigmask attribute of spawn attributes object

SYNOPSIS

       #include <signal.h>
       #include <spawn.h>

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

       int posix_spawnattr_setsigmask(posix_spawnattr_t *restrict 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

       Upon successful completion, posix_spawnattr_getsigmask() returns 0 and stores the value of the spawn-sigmask attribute  of  attr  into  the
       object referenced by the sigmask parameter.  Otherwise, an error number is returned to indicate the error.

       Upon successful completion, posix_spawnattr_setsigmask() returns 0. Otherwise, an error number is returned to indicate the error.

ERRORS

       These functions may fail if:

       EINVAL	       The value specified by attr is invalid.

       The posix_spawnattr_setsigmask() function may fail if:

       EINVAL	       The value of the attribute being set is not valid.
