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.  Set-
                 ting 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 implementa-
       tion-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 implementa-
       tion-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 imple-
       mentation-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.
