    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>, <signal.h>, and <sys/types.h> headers.
