Subject: topfish maxmatch: use cgraph wrappers for allocation
X-Git-Tag: 6.0.2~32^2~9
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=01aa6d376df45fe47bdaf616979abe5b4921439b;p=graphviz

topfish maxmatch: use cgraph wrappers for allocation

The lib/cgraph/alloc.h wrappers are similar to the older lib/common/memory.h
wrappers except (1) they are header-only and (2) they live in a directory
(cgraph) that is at the root of the dependency tree. The long term plan is to
replace all use of lib/common/memory.h with lib/cgraph/alloc.h.
