Subject: Since NetWare CLib does not implement file locking through fcntl() or flock(),
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a6e7114f9dce1abc4eaba528777704edd5013416;p=thirdparty%2Fapache%2Fhttpd.git

Since NetWare CLib does not implement file locking through fcntl() or flock(),
used a semaphore to simulate the file locking behavior.
