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

NAME
       posix_spawnattr_getsigdefault,	posix_spawnattr_setsigdefault	-   get   and	set   the
       spawn-sigdefault attribute of a spawn attributes object (ADVANCED REALTIME)

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

       int posix_spawnattr_getsigdefault(const posix_spawnattr_t *
	      restrict attr, sigset_t *restrict sigdefault);
       int posix_spawnattr_setsigdefault(posix_spawnattr_t *restrict attr,
	      const sigset_t *restrict sigdefault);

DESCRIPTION
       The posix_spawnattr_getsigdefault() function shall obtain the value  of	the  spawn-sigde-
       fault attribute from the attributes object referenced by attr.

       The  posix_spawnattr_setsigdefault()  function shall set the spawn-sigdefault attribute in
       an initialized attributes object referenced by attr.

       The spawn-sigdefault attribute represents the set of signals to be forced to default  sig-
       nal  handling in the new process image (if POSIX_SPAWN_SETSIGDEF is set in the spawn-flags
       attribute) by a spawn operation. The default value of this attribute  shall  be	an  empty
       signal set.

RETURN VALUE
       Upon  successful  completion,  posix_spawnattr_getsigdefault() shall return zero and store
       the value of the spawn-sigdefault attribute of attr into  the  object  referenced  by  the
       sigdefault parameter; otherwise, an error number shall be returned to indicate the error.

       Upon  successful completion, posix_spawnattr_setsigdefault() 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_setsigdefault() 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.
