POSIX_SPAWNATTR_GETSIGMASK(P)	    POSIX Programmer's Manual	    POSIX_SPAWNATTR_GETSIGMASK(P)

NAME
       posix_spawnattr_getsigmask,  posix_spawnattr_setsigmask	-  get	and set the spawn-sigmask
       attribute of a spawn attributes object (ADVANCED REALTIME)

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 shall obtain  the  value  of  the  spawn-sigmask
       attribute from the attributes object referenced by attr.

       The posix_spawnattr_setsigmask() function shall set the spawn-sigmask attribute in an ini-
       tialized 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 VALUE
       Upon successful completion, posix_spawnattr_getsigmask() shall return zero and  store  the
       value  of  the  spawn-sigmask  attribute of attr into the object referenced by the sigmask
       parameter; otherwise, an error number shall be returned to indicate the error.

       Upon successful completion, posix_spawnattr_setsigmask() shall return zero; otherwise,  an
       error number shall be 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.

       The following sections are informative.

EXAMPLES
       None.

APPLICATION USAGE
       These  functions  are part of the Spawn option and need not be provided on all implementa-
       tions.

RATIONALE
       None.

FUTURE DIRECTIONS
       None.
