FcConfigEnableHome: controls use of the home directory.
NAME
FcConfigEnableHome - controls use of the home directory.
SYNOPSIS
#include <fontconfig/fontconfig.h>
FcBool FcConfigEnableHome (FcBool enable);
DESCRIPTION
If enable is FcTrue, then Fontconfig will use various files which are specified relative to the user's home directory (using the ~ notation in the configuration). When enable is FcFalse, then all use of the home directory in these contexts will be disabled. The previous setting of the value is returned.
