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.
