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.

EXAMPLES

       None.

APPLICATION USAGE

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

RATIONALE

       None.

FUTURE DIRECTIONS

       None.
