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.
Specifies the connection
to the X server.
Specifies the array of strings you want to free.
the number of directories in the path.
Returns the number of strings in
the font path array.
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 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.
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.
function frees the data allocated by XGetFontPath.
- 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.
