XSetFontPath(3)


NAME

   XSetFontPath, XGetFontPath, XFreeFontPath - set, get, or free the font
   search path

SYNTAX

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

   char **XGetFontPath(Display *display, int *npaths_return);

   int XFreeFontPath(char **list);

ARGUMENTS

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

   display   Specifies the connection to the X server.

   list      Specifies the array of strings you want to free.

   ndirs     Specifies the number of directories in the path.

   npaths_return
             Returns the number of strings in the font path array.

DESCRIPTION

   The XSetFontPath function defines the directory search path for font
   lookup.  There is only one search path per X server, not one per
   client.  The encoding and interpretation of the strings are
   implementation-dependent, but typically they specify directories or
   font servers to be searched in the order listed.  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 subsequent opens of
   that font to see if the underlying font file has changed.  However,
   when the font path is changed, the X server is guaranteed to flush all
   cached information about fonts for which there currently are no
   explicit resource IDs allocated.  The meaning of an error from this
   request is implementation-dependent.

   XSetFontPath can generate a BadValue error.

   The XGetFontPath function allocates and returns an array of strings
   containing the search path.  The contents of these strings are
   implementation-dependent and are not intended to be interpreted by
   client applications.  When it is no longer needed, the data in the font
   path should be freed by using XFreeFontPath.

   The XFreeFontPath function frees the data allocated by XGetFontPath.

DIAGNOSTICS

   BadValue  Some numeric value falls outside the range of values accepted
             by the request.  Unless a specific range is specified for an
             argument, the full range defined by the argument's type is
             accepted.  Any argument defined as a set of alternatives can
             generate this error.
