.SH ARGUMENTS
|
|
.IP \fIdirectories\fP 1i
|
|
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.
|
|
.IP \fIdisplay\fP 1i
|
|
Specifies the connection to the X server.
|
|
.IP \fIlist\fP 1i
|
|
Specifies the array of strings you want to free.
|
|
.IP \fIndirs\fP 1i
|
|
Specifies the number of directories in the path.
|
|
.IP \fInpaths_return\fP 1i
|
|
Returns the number of strings in the font path array.
|
|
.SH DESCRIPTION
|
|
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 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.
|
|
.LP
|
|
.ZN XSetFontPath
|
|
can generate a
|
|
.ZN BadValue
|
|
error.
|
|
.LP
|
|
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 .
|
|
.LP
|
|
The
|
|
.ZN XFreeFontPath
|
|
function
|
|
frees the data allocated by
|
|
.ZN XGetFontPath .
|
|
.SH DIAGNOSTICS
|
|
.TP 1i
|
|
.ZN 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.
