Description of FcStrDirname is absent in the official documentation of
fontconfig-2.5.92. At the same time the source documentation contains
description of the function.
The problem is a consequence of a misprint in the format of the source
documentation file 'fcstring.fncs'. The finish mark of description of the
previous function is absent.
@DESC@
This is just a wrapper around free(3) which helps track memory usage of
strings within the fontconfig library.
