 Name

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

 Syntax


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

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


    XFreeFontPath(list)
          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.

    npathsreturn  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 is implementation depen-
    dent, but typically they specify directories or font servers to be
    searched in the order listed.  An X server is permitted to cache font in-
    formation 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 under-
    lying 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 mean-
    ing 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 con-
    taining the search path.  The contents of these strings are implementa-
    tion dependent and are not intended to be interpreted by client applica-
    tions.  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.
