+.SH NAME
+FcConfigGetFilename \- Find a config file
+.SH SYNOPSIS
+.nf
+\fB#include <fontconfig/fontconfig.h>
+.sp
+FcChar8 * FcConfigGetFilename (FcConfig *\fIconfig\fB, const FcChar8 *\fIname\fB);
+.fi\fR
+.SH "DESCRIPTION"
+.PP
+Given the specified external entity name, return the associated filename.
+This provides applications a way to convert various configuration file
+references into filename form.
+.PP
+A null or empty \fIname\fR indicates that the default configuration file should
+be used; which file this references can be overridden with the
+FONTCONFIG_FILE environment variable. Next, if the name starts with \fI~\fR, it
+refers to a file in the current users home directory. Otherwise if the name
+doesn't start with '/', it refers to a file in the default configuration
+directory; the built-in default directory can be overridden with the
+FONTCONFIG_PATH environment variable.
+.PP
+The result of this function is affected by the FONTCONFIG_SYSROOT environment variable or equivalent functionality.

+From: Akira TAGOH <akira@tagoh.org>
+Date: Mon, 23 Mar 2020 14:03:47 +0900
+Subject: [PATCH] Fix assertion in FcCacheFini() again
+ 
+The previous fix in fbc05949ef52c8a8d69233eed77f6636dffec280 was wrong. reverting.
+ 
+When reading older caches, FcDirCacheMapHelper() returns FcFalse and
+it became the return value from FcDirCacheProcess() too, which is wrong.
+Actually one of calls for FcDirCacheMapHelper() should be successfully
+finished and closure should have a valid pointer for cache.
+ 
+Due to this, the proper finalization process wasn't running against
+cache in closure.
+ 
+Fixes https://gitlab.freedesktop.org/fontconfig/fontconfig/issues/227
