Subject: Use ptrdiff_t instead of int for mem_node data offset
X-Git-Tag: SQUID_3_1_9~37
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e8c45a2d7fb2aa3c7b7973332898167342dcca1d;p=thirdparty%2Fsquid.git

Use ptrdiff_t instead of int for mem_node data offset

This is the correct POSIX type for storing pointer offsets.

TODO: The store API use of mem_node needs some design fixes to obsolete
      these offsets entirely.
