NAME

     posix_spawnattr_setsigdefault posix_spawnattr_getsigdefault -- set or get the spawn-sigdefault attribute on a posix_spawnattr_t

SYNOPSIS

     #include <spawn.h>

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

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

DESCRIPTION

     The posix_spawnattr_setsigdefault() function sets the sigdefault on the attributes object referenced by attr.

     The posix_spawnattr_getsigdefault() function retrieves the sigdefault on the attributes object referenced by attr.

     The argument sigdefault is the set of signals to be returned to default behaviour in the new process on creation if the POSIX_SPAWN_SETSIGDEF
     flag is set in the posix_spawnattr_t.  It's default value must be set via a call to posix_spawnattr_setflags(3) or the behaviour is unde-
     fined.

RETURN VALUES

     On success, these functions return 0; on failure they return an error number from <errno.h>.  Additionally, if successful,
     posix_spawnattr_getsigdefault() will modify the contents of the sigdefault parameter with the current attribute value.

ERRORS

     These functions may fail if:

     [EINVAL]		The value specified by attr is invalid.

     [EINVAL]		The value of attr is invalid.

NAME

       posix_spawnattr_getsigdefault, posix_spawnattr_setsigdefault - get and set spawn-sigdefault attribute of spawn attributes object

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 obtains the value of the spawn-sigdefault attribute from the attributes object referenced by
       attr.

       The posix_spawnattr_setsigdefault() function sets 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 is an empty signal
       set.

RETURN VALUES

       Upon successful completion, posix_spawnattr_getsigdefault() returns 0 and stores the value of the spawn-sigdefault attribute of	attr  into
       the object referenced by the sigdefault parameter.  Otherwise, an error number is returned to indicate the error.

       Upon successful completion, posix_spawnattr_setsigdefault() returns 0. Otherwise, an error number is 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.
