NAME

       Xfontcache - X-TrueType font cache extension client library

SYNOPSIS

       #include <X11/extensions/FontCache.h>

       typedef struct {
	    long	   himark;
	    long	   lowmark;
	    long	   balance;
       } FontCacheSettings, *FontCacheSettingsPtr;

       struct cacheinfo {
	    long	   hits;
	    long	   misshits;
	    long	   purged;
	    long	   usage;
       };

       typedef struct {
	    long	   purge_runs;
	    long	   purge_stat;
	    long	   balance;
	    struct cacheinfof;
	    struct cacheinfov;
       } FontCacheStatistics, *FontCacheStatisticsPtr;

       Bool FontCacheQueryExtension(Display *dpy, int *event_basep, int *error_basep);

       Status FontCacheQueryVersion(Display *dpy, int *major_versionp, int *minor_versionp);

       Status FontCacheGetCacheSettings(Display *dpy, FontCacheSettings *cache info);

       Status FontCacheChangeCacheSettings(Display *dpy, FontCacheSettings *cache info);

       Status FontCacheGetCacheStatistics(Display *dpy, FontCacheStatistics *cache statistics info);

DESCRIPTION

       FontCache is an extension that is used by X-TrueType to cache informations about fonts.

       FontCacheQueryExtension returns True if the FontCache extension is available on the given display.  A client must call FontCacheQueryExten-
       sion before calling any other Xfontcache function in order to negotiate a compatible protocol version; otherwise the client will get  unde-
       fined 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.
