PROLOG <\/a> <\/h2>\n

This manual page is part of the POSIX Programmer\u2019s 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.<\/p>\n

NAME <\/a> <\/h2>\n

posix_spawnattr_getsigmask, posix_spawnattr_setsigmask \u2014 get and set the spawn-sigmask attribute of a spawn attributes object (ADVANCED REALTIME<\/b>)<\/p>\n

SYNOPSIS <\/a> <\/h2>\n

#include
#include <\/p>\n

int posix_spawnattr_getsigmask(const posix_spawnattr_t *restrict attr<\/i>,
sigset_t *restrict sigmask<\/i>);
int posix_spawnattr_setsigmask(posix_spawnattr_t *restrict attr<\/i>,
const sigset_t *restrict sigmask<\/i>);<\/p>\n

DESCRIPTION <\/a> <\/h2>\n

The posix_spawnattr_getsigmask<\/i>() function shall obtain the value of the spawn-sigmask<\/i> attribute from the attributes object referenced by attr<\/i>.<\/p>\n

The posix_spawnattr_setsigmask<\/i>() function shall set the spawn-sigmask<\/i> attribute in an initialized attributes object referenced by attr<\/i>.<\/p>\n

The spawn-sigmask<\/i> 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<\/i> attribute). The default value of this attribute is unspecified.<\/p>\n

RETURN VALUE <\/a> <\/h2>\n

Upon successful completion, posix_spawnattr_getsigmask<\/i>() shall return zero and store the value of the spawn-sigmask<\/i> attribute of attr<\/i> into the object referenced by the sigmask<\/i> parameter; otherwise, an error number shall be returned to indicate the error.<\/p>\n

Upon successful completion, posix_spawnattr_setsigmask<\/i>() shall return zero; otherwise, an error number shall be returned to indicate the error.<\/p>\n

ERRORS <\/a> <\/h2>\n

These functions may fail if:<\/p>\n\n\n
<\/td>\n\n

EINVAL<\/b><\/p>\n<\/td>\n

<\/td>\n\n

The value specified by attr<\/i> is invalid.<\/p>\n<\/td>\n

 <\/td>\n<\/tr>\n<\/table>\n

The posix_spawnattr_setsigmask<\/i>() function may fail if:<\/p>\n\n\n
<\/td>\n\n

EINVAL<\/b><\/p>\n<\/td>\n

<\/td>\n\n

The value of the attribute being set is not valid.<\/p>\n<\/td>\n

The following sections are informative.<\/i><\/p>\n

EXAMPLES <\/a> <\/h2>\n

None.<\/p>\n

APPLICATION USAGE <\/a> <\/h2>\n

These functions are part of the Spawn option and need not be provided on all implementations.<\/p>\n

RATIONALE <\/a> <\/h2>\n

None.<\/p>\n

FUTURE DIRECTIONS <\/a> <\/h2>\n

None.<\/p>\n
