Lionel Sambuc 84d9c625bf Synchronize on NetBSD-CVS (2013/12/1 12:00:00 UTC)
- Fix for possible unset uid/gid in toproto
 - Fix for default mtree style
 - Update libelf
 - Importing libexecinfo
 - Resynchronize GCC, mpc, gmp, mpfr
 - build.sh: Replace params with show-params.
     This has been done as the make target has been renamed in the same
     way, while a new target named params has been added. This new
     target generates a file containing all the parameters, instead of
     printing it on the console.
 - Update test48 with new etc/services (Fix by Ben Gras <ben@minix3.org)
     get getservbyport() out of the inner loop

.Sh SYNOPSIS
.In spawn.h
.Ft int
.Fn posix_spawnattr_getflags "const posix_spawnattr_t *restrict attr" "short *restrict flags"
.Ft int
.Fn posix_spawnattr_setflags "posix_spawnattr_t *attr" "short flags"
.Sh DESCRIPTION
The
.Fn posix_spawnattr_getflags
function obtains the value of the spawn-flags attribute from the

are to be changed in the new process image when invoking
.Fn posix_spawn
or
.Fn posix_spawnp .
It is the bitwise-inclusive OR of zero or more of the following flags
(see
.Fn posix_spawn ) :
.Bl -tag -offset indent
.It Dv POSIX_SPAWN_RESETIDS
.It Dv POSIX_SPAWN_SETPGROUP
