Subject: api.c: Export cgroup_build_tasks_procs_path()
X-Git-Tag: v2.0.rc1~14^2~1
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4f4e01062a9f22ea960fb7a7c650f9fbfcc51624;p=thirdparty%2Flibcgroup.git

api.c: Export cgroup_build_tasks_procs_path()

Make cgroup_build_tasks_procs_path() available to
libcgroup.la library users (i.e. the libcgroup tools).

This change will be used in the next commit so that
cgsnapshot can properly read the tasks/procs file.
