POSIX_SPAWNATTR_GETSIGMASK(3P)OSIX Programmer's ManuPaOlSIX_SPAWNATTR_GETSIGMASK(3)



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

NAME
       posix_spawnattr_getsigmask, posix_spawnattr_setsigmask -- get and set
       the spawn-sigmask attribute of a spawn attributes object (ADVANCED
       REALTIME)

SYNOPSIS
       #include <signal.h>
       #include <spawn.h>

       int posix_spawnattr_getsigmask(const posix_spawnattr_t *restrict attr,
           sigset_t *restrict sigmask);
       int posix_spawnattr_setsigmask(posix_spawnattr_t *restrict attr,
           const sigset_t *restrict sigmask);

DESCRIPTION
       The posix__spawnattr__getsigmask() function shall obtain the value of the
       spawn-sigmask attribute from the attributes object referenced by attr.

       The posix__spawnattr__setsigmask() function shall set the spawn-sigmask
       attribute in an initialized attributes object referenced by attr.

       The spawn-sigmask attribute represents the signal mask in effect in the
       new process image of a spawn operation (if POSIX_SPAWN_SETSIGMASK is
       set in the spawn-flags attribute). The default value of this attribute
       is unspecified.

RETURN VALUE
       Upon successful completion, posix__spawnattr__getsigmask() shall return
       zero and store the value of the spawn-sigmask attribute of attr into
       the object referenced by the sigmask parameter; otherwise, an error
       number shall be returned to indicate the error.

       Upon successful completion, posix__spawnattr__setsigmask() 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__setsigmask() function may fail if:

       EINVAL The value of the attribute being set is not valid.

       The following sections are informative.

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.
