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.

list restores the default path defined for the X server.

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.
