POSIX_SPAWNATTR_GETSIGMASK(3P)X Programmer's Manual_SPAWNATTR_GETSIGMASK(3P)
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.
posix_spawnattr_getsigmask, posix_spawnattr_setsigmask — get and set
the spawn-sigmask attribute of a spawn attributes object (ADVANCED
REALTIME)
#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);
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.
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.
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.
None.
These functions are part of the Spawn option and need not be provided
on all implementations.
None.
