DESCRIPTION
FontCache is an extension that is used by X-TrueType to cache informa-
tions about fonts.
FontCacheQueryExtension returns True if the FontCache extension is
available on the given display. A client must call FontCacheQueryEx-
tension before calling any other Xfontcache function in order to nego-
tiate a compatible protocol version; otherwise the client will get
undefined behavior (Xfontcache may or may not work).
FontCacheQueryVersion returns True if the request succeeded; the values
of the major and minor protocol versions supported by the server are
returned in major_versionp and minor_versionp .
FontCacheGetCacheSettings should be documented here. Returns True on
success or False on failure.
FontCacheChangeCacheSettings should be documented here. Returns True
on success or False on failure.
FontCacheGetCacheStatistics should be documented here. Returns True on
success or False on failure.
ERRORS
FontCacheChangeCacheSettings will return BadValue if passed an illegal
parameters for lowmark, himark or balance fields.
