Originální popis anglicky: spawn.h - spawn ( ADVANCED REALTIME)

Návod, kniha: POSIX Programmer's Manual

STRUČNĚ

#include <spawn.h>

POPIS / INSTRUKCE

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>, <signal.h>, and <sys/types.h> headers.
The following sections are informative.
