Subject: gvc: add storage-class attribute declaration of gvrender_ptf to gvcproc.h
X-Git-Tag: 3.0.0~94^2~9
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=abf2f1ac25c7052728b21e487de2e8757107ebcb;p=graphviz

gvc: add storage-class attribute declaration of gvrender_ptf to gvcproc.h

This will allow removing this symbol from gvc.def in an upcoming commit.

Note that no other symbols from gvcproc.h were exported from gvc.def,
hence the attributes are applied only to gvrender_ptf.
