[sr-dev] git:kamailio_3.0: core rpc: core.shmmem can take an optional size parameter

Module: sip-router Branch: kamailio_3.0 Commit: 306ef4698b53fcb616ef53baa7dead895771e46d URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=306ef46… Author: Andrei Pelinescu-Onciul <andrei(a)iptel.org> Committer: Daniel-Constantin Mierla <miconda(a)gmail.com> Date: Thu Nov 12 17:24:27 2009 +0100 core rpc: core.shmmem can take an optional size parameter core.shmmem can take now an optional size parameter, which can have one of the following values: b - bytes, k or kb - kilobytes, m or mb - megabytes, g or gb - gigabytes. By default (no parameter) the values displayed are in bytes. Note that when using something different from bytes the value are truncated (no floating point). The new parameter can be used as workaround on 64 bits systems when sr is started with more then 2Gb of memory (due to the RPC interface limitation to int32 in this case the values displayed would be negative or 0).
