NAME
atsutil -- font registration system utility SYNOPSIS
atsutil autoactivation [-DdeaRh] [path] atsutil databases [-remove | -removeUser] atsutil fontprotection [-on | -off] [-get] [-files] [-fonts] atsutil server [-ping | -shutdown] atsutil help DESCRIPTION
atsutil tool controls some aspects of the font registration system. It may be used to modify font auto activation settings, font protection settings, remove font registration databases and caches, or restart the font registration daemon. autoactivation modifies font auto activation settings globally or for a specific application. databases will remove fontd System or User databases along with any cache files. Removing databases may cause the loss of font registration state: fonts activated outside the standard font directories, font faces disabled, and font libraries. New databases will be regenerated from fonts installed the standard font directories after the user logs out, restarts, or the fontd server is restarted. fontprotection overrides System font protection settings. server queries the status of fontd or shutdowns the fontd. Shutting down the fontd will spawn a new fontd. Shutting down the server is NOT recommended and will likely lead to misrendered text or application crashes. OPTIONS
autoactivation [-DdeaRh] [path] -D set font auto activation setting to default. -d is specified, then set font auto activation setting to disabled. -e is specified, then set font auto activation setting to enabled. -a is specified, then set font auto activation setting to ask. -R is specified, then reset font auto activation setting to default. -h is specified, then display help information. -path with options is specified, then set font auto activation setting locally for application. Otherwise, setting is global in scope. Note, path without options will return current font auto activation setting for application. databases [-remove | -removeUser] -remove remove fontd databases for active user and system (used when no one is logged in and some background processes). -removeUser remove fontd databases for the active user only. fontprotection [-on | -off] [-get] [-files] [-fonts] -on enable System font protection. -off disable System font protection. -get return System font protection setting. -files prints list of protected font files. -fonts prints list of protected font faces (Postscript names). server [-ping | -shutdown] -ping query running fontd. -shutdown shutdown fontd and spawn a new fontd. NOTE: this action is not recommended. See above. SEE ALSO

Name
  XSetFontPath - set the font search path.

Synopsis
  XSetFontPath(display, directories, ndirs)
	Display *display;
	char **directories;
	int ndirs;

Arguments
  display   Specifies a connection to an X server; returned from XOpenDisplay().

  directories
	    Specifies the directory path used to look for the font.  Setting the path to the empty list restores the default path defined for
	    the X server.

  ndirs     Specifies the number of directories in the path.

Description
  XSetFontPath() defines the directory search path for font lookup for all clients.  Therefore the user  should  construct  a  new  directory
  search  path	carefully  by adding to the old directory search path obtained by XGetFontPath().  Passing an invalid path can result in pre-
  venting the server from accessing any fonts.	Also avoid restoring the default path, since some other client may have changed the  path  on
  purpose.

  The  interpretation  of the strings is operating-system-dependent, but they are intended to specify directories to be searched in the order
  listed.  Also, the contents of these strings are operating system specific and are not intended to be used by client applications.

  An X server is permitted to cache font information internally, for example, it might cache an entire font from a file and not check on sub-
  sequent  opens of that font to see if the underlying font file has changed.  However, when the font path is changed the X server is guaran-
  teed to flush all cached information about fonts for which there currently are no explicit resource IDs allocated.

  The meaning of errors from this request is implementation-dependent.

Errors
  BadValue
