POSIX_SPAWNATTR_GETFLAGS(3P)SIX Programmer's ManualIX_SPAWNATTR_GETFLAGS(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_getflags, posix_spawnattr_setflags — get and set the
spawn-flags attribute of a spawn attributes object (ADVANCED
REALTIME)
#include <spawn.h>
int posix_spawnattr_getflags(const posix_spawnattr_t *restrict attr,
short *restrict flags);
int posix_spawnattr_setflags(posix_spawnattr_t *attr, short flags);
The posix_spawnattr_getflags() function shall obtain the value of the
spawn-flags attribute from the attributes object referenced by attr.
The posix_spawnattr_setflags() function shall set the spawn-flags
attribute in an initialized attributes object referenced by attr.
The spawn-flags attribute is used to indicate which process
attributes are to be changed in the new process image when invoking
posix_spawn() or posix_spawnp(). It is the bitwise-inclusive OR of
zero or more of the following flags:
POSIX_SPAWN_RESETIDS
POSIX_SPAWN_SETPGROUP
POSIX_SPAWN_SETSIGDEF
POSIX_SPAWN_SETSIGMASK
POSIX_SPAWN_SETSCHEDPARAM
POSIX_SPAWN_SETSCHEDULER
These flags are defined in <spawn.h>. The default value of this
attribute shall be as if no flags were set.
Upon successful completion, posix_spawnattr_getflags() shall return
zero and store the value of the spawn-flags attribute of attr into
the object referenced by the flags parameter; otherwise, an error
number shall be returned to indicate the error.
Upon successful completion, posix_spawnattr_setflags() 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_setflags() 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.
