PROLOG         top

       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         top

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

SYNOPSIS         top

       #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         top

       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         top

       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         top

       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         top

       None.

APPLICATION USAGE         top

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

RATIONALE         top

       None.

FUTURE DIRECTIONS         top

       None.
