POSIX_SPAWNATTR_GETSIGDEFAUPOSIX)Programmer'sPOSIX_SPAWNATTR_GETSIGDEFAULT(3P)

PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the	 corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.

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-sigde‐
       fault 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.

       The following sections are informative.

EXAMPLES

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

RATIONALE
       None.

FUTURE DIRECTIONS
       None.
