.SH DESCRIPTION

|
.\" $Header: XSetFontPath.d,v 1.2 88/06/11 07:53:13 mento Exp $
|
|
The
|
|
.ZN 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.
|
|
.LP
|
|
.ZN XSetFontPath
|
|
can generate a
|
|
.ZN BadValue
|
|
error.
|
|
.LP
|
|
.\" $Header: XGetFontPath.d,v 1.3 88/04/23 09:36:29 mento Exp $
|
|
The
|
|
.ZN 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
|
|
.ZN XFreeFontPath .

|

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.
