FlushFonts

The FlushFonts function erases the Font Manager's memory caches.

FUNCTION FlushFonts: OSErr;

DESCRIPTION

The FlushFonts function erases all of the Font Manager's memory caches. Your application doesn't need this function unless it directly manipulates data in the outline font resource. Font Manager caches include the width tables, the bitmaps created from the outlines of the outline font resource, the calculations for the outlines, and a small cache of font family resources that have been read into memory.
