Subject: admin/build-doc: add optional "_" prefix before function names to match
X-Git-Tag: v16.0.0~20^2~1
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=c20e074efa2d3b982e5190bc99d1909937df7f9b;p=ceph.git

admin/build-doc: add optional "_" prefix before function names to match

as compilers targeting ELF does not add the leading "_" to symbol names,
while clang on OSX always do this.

and remove the underscore from the symbol name when generating the
function name, as the compiler will add it back for us.
