svn commit: r758406 - /httpd/httpd/trunk/server/mpm_common.c

[tr...@apache.org]

Author: trawick
Date: Wed Mar 25 18:57:09 2009
New Revision: 758406

URL: http://svn.apache.org/viewvc?rev=758406&view=rev
Log:
fix mpm_get_name hook

a string can't be used as the declined value since the hook macro must compare 
retcodes from hooks with that declined value

(thanks, gcc/Joe)

accommodate in ap_show_mpm() since we don't want to return NULL to the caller of
this simple API
