NAME

       posix_spawnattr_getflags, posix_spawnattr_setflags — get and set the spawn-flags attribute
       of a spawn attributes object (ADVANCED REALTIME)

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  shall  obtain  the  value  of  the  spawn-flags
       attribute from the attributes object referenced by attr.

       The  posix_spawnattr_setflags()  function  shall  set  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()  or posix_spawnp().  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

       These flags are defined in <spawn.h>.  The default value of this attribute shall be as  if
       no flags were set.

RETURN VALUE

       Upon  successful  completion,  posix_spawnattr_getflags()  shall return zero and store the
       value of the spawn-flags attribute of  attr  into  the  object  referenced  by  the  flags
       parameter; otherwise, an error number shall be returned to indicate the error.

       Upon  successful  completion,  posix_spawnattr_setflags() shall return zero; otherwise, an
       error number shall be 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.

       The following sections are informative.

EXAMPLES

       None.

APPLICATION USAGE

       These  functions  are  part  of  the  Spawn  option  and  need  not  be  provided  on  all
       implementations.

RATIONALE

       None.

FUTURE DIRECTIONS

       None.
