       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.

       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.

       Thefollowingsectionsareinformative.

       may differ (consult the corresponding Linux manual page for details of Linux behavior), or the  interface
       may not be implemented on Linux.

       None.

       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.
