Subject: Add ap_append_pid(); This is performed enough to warrant
X-Git-Tag: 2.3.0~3031
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d81de0d9b3104a0a139ba5bcc51aba8521249afe;p=thirdparty%2Fapache%2Fhttpd.git

Add ap_append_pid(); This is performed enough to warrant
a function I think, especially with the fact that
the mapping of getpid() to APR_PID_T_FMT isn't
consistant in some areas.
