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-sigdefault 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 signal 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.

APPLICATION USAGE

       These functions are part of the Spawn option and need not be provided on all implementations.

RATIONALE

       None.

FUTURE DIRECTIONS

       None.
