# FcConfigGetFilename(3)

Find a config file

## NAME

FcConfigGetFilename - Find a config file

## SYNOPSIS

**#include \<fontconfig/fontconfig.h\>**

**FcChar8 \* FcConfigGetFilename (FcConfig \****config***, const FcChar8 \****name***);**

## DESCRIPTION

Given the specified external entity name, return the associated filename. This provides applications a way to convert various configuration file references into filename form.

A null or empty *name* 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 *~*, 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.

The result of this function is affected by the FONTCONFIG\_SYSROOT environment variable or equivalent functionality.
