NAME
XSetFontPath, XGetFontPath, XFreeFontPath - 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.
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 is 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.
