POSIX_SPAWNATTR_GETFLAGS(3C)POSIX_SPAWNATTR_GETFLAGS(3C)NAME
posix_spawnattr_getflags, posix_spawnattr_setflags - get and set spawn-
flags attribute of spawn attributes object
SYNOPSIS
#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);
DESCRIPTION
The posix_spawnattr_getflags() function obtains the value of the spawn-
flags attribute from the attributes object referenced by attr.
The posix_spawnattr_setflags() function sets 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(3C) or posix_spawnp(3C). 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
POSIX_SPAWN_NOSIGCHLD_NP
POSIX_SPAWN_WAITPID_NP
POSIX_SPAWN_NOEXECERR_NP
These flags are defined in <spawn.h>. The default value of this
attribute is as if no flags were set.
RETURN VALUES
Upon successful completion, posix_spawnattr_getflags() returns 0 and
stores the value of the spawn-flags attribute of attr into the object
referenced by the flags parameter. Otherwise, an error number is
returned to indicate the error.
Upon successful completion, posix_spawnattr_setflags() returns 0. Oth‐
erwise, an error number is returned to indicate the error.
ERRORS
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.
