XFreeFontPath - set, get, or free the font search path
char **XGetFontPath(display, npaths_return)
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.
- 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.
- Specifies the connection to the X server.
the array of strings you want to free.
- Specifies the number of directories
in the path.
- Returns the number of strings in the font path
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.
- 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
