NAME
FcConfigSetSysRoot - Set the system root directory
SYNOPSIS
#include <fontconfig/fontconfig.h>
void FcConfigSetSysRoot (FcConfig *config, const FcChar8 *sysroot);
DESCRIPTION
Set 'sysroot' as the system root directory. fontconfig prepend 'sysroot' to the cache directories in
order to allow people to generate caches at the build time. Note that this causes changing current
config. i.e. this function calls FcConfigSetCurrent() internally.
