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.
