XSetFontPath(3X11)       XLIB FUNCTIONS        XSetFontPath(3X11)

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 infor-
     mation 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. How-
     ever, 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 allo-
     cated. 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.

XSetFontPath(3X11)       XLIB FUNCTIONS        XSetFontPath(3X11)

     The XFreeFontPath function frees the data allocated by XGet-
     FontPath.

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 gen-
               erate this error.
