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.
Имя (Name)
spawn.h — spawn (ADVANCED REALTIME)
Синопсис (Synopsis)
#include <spawn.h>
Описание (Description)
The <spawn.h> header shall define the posix_spawnattr_t and
posix_spawn_file_actions_t types used in performing spawn
operations.
The <spawn.h> header shall define the mode_t and pid_t types as
described in <sys/types.h>.
The <spawn.h> header shall define the sigset_t type as described
in <signal.h>.
The tag sched_param shall be declared as naming an incomplete
structure type, the contents of which are described in the
<sched.h> header.
The <spawn.h> header shall define the following symbolic
constants for use as the flags that may be set in a
posix_spawnattr_t object using the posix_spawnattr_setflags()
function:
POSIX_SPAWN_RESETIDS
POSIX_SPAWN_SETPGROUP
POSIX_SPAWN_SETSCHEDPARAM
POSIX_SPAWN_SETSCHEDULER
POSIX_SPAWN_SETSIGDEF
POSIX_SPAWN_SETSIGMASK
The following shall be declared as functions and may also be
defined as macros. Function prototypes shall be provided.
int posix_spawn(pid_t *restrict, const char *restrict,
const posix_spawn_file_actions_t *,
const posix_spawnattr_t *restrict, char *const [restrict],

Inclusion of the <spawn.h> header may make visible symbols
defined in the <sched.h> and <signal.h> headers.
