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.
