<spawn.h>(P)			    POSIX Programmer's Manual			     <spawn.h>(P)

NAME
       spawn.h - spawn (ADVANCED REALTIME)

SYNOPSIS
       #include <spawn.h>

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 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],
			char *const [restrict]);
	      int   posix_spawn_file_actions_addclose(posix_spawn_file_actions_t *,
			int);
	      int   posix_spawn_file_actions_adddup2(posix_spawn_file_actions_t *,
			int, int);
	      int   posix_spawn_file_actions_addopen(posix_spawn_file_actions_t *restrict,
			int, const char *restrict, int, mode_t);
	      int   posix_spawn_file_actions_destroy(posix_spawn_file_actions_t *);
	      int   posix_spawn_file_actions_init(posix_spawn_file_actions_t *);
	      int   posix_spawnattr_destroy(posix_spawnattr_t *);
	      int   posix_spawnattr_getsigdefault(const posix_spawnattr_t *restrict,
			sigset_t *restrict);
	      int   posix_spawnattr_getflags(const posix_spawnattr_t *restrict,
			short *restrict);
	      int   posix_spawnattr_getpgroup(const posix_spawnattr_t *restrict,
			pid_t *restrict);

	      int   posix_spawnattr_getschedparam(const posix_spawnattr_t *restrict,
			struct sched_param *restrict);
	      int   posix_spawnattr_getschedpolicy(const posix_spawnattr_t *restrict,
			int *restrict);

	      int   posix_spawnattr_getsigmask(const posix_spawnattr_t *restrict,
			sigset_t *restrict);
	      int   posix_spawnattr_init(posix_spawnattr_t *);
	      int   posix_spawnattr_setsigdefault(posix_spawnattr_t *restrict,
			const sigset_t *restrict);
	      int   posix_spawnattr_setflags(posix_spawnattr_t *, short);
	      int   posix_spawnattr_setpgroup(posix_spawnattr_t *, pid_t);

	      int   posix_spawnattr_setschedparam(posix_spawnattr_t *restrict,
			const struct sched_param *restrict);
	      int   posix_spawnattr_setschedpolicy(posix_spawnattr_t *, int);

	      int   posix_spawnattr_setsigmask(posix_spawnattr_t *restrict,
			const sigset_t *restrict);
	      int   posix_spawnp(pid_t *restrict, const char *restrict,
			const posix_spawn_file_actions_t *,
			const posix_spawnattr_t *restrict,
			char *const [restrict], char *const [restrict]);

       Inclusion of the <spawn.h> header may make visible symbols defined in the <sched.h>, <sig-
       nal.h>, and <sys/types.h> headers.
