XSetFontPath, XGetFontPath, XFreeFontPath - set, get, or free the font search path
2. SYNTAX ▲
int XSetFontPath(Display *display, char **directories, int ndirs); char **XGetFontPath(Display *display, int *npaths_return); int XFreeFontPath(char **list);
3. ARGUMENTS ▲
directories 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.
display 1i Specifies the connection to the X server.
list 1i Specifies the array of strings you want to free.
ndirs 1i Specifies the number of directories in the path.
npaths_return 1i Returns the number of strings in the font path array.
4. 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.
.ZN XSetFontPath can generate a .ZN BadValue error.
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 .
The .ZN XFreeFontPath function frees the data allocated by .ZN XGetFontPath .
5. DIAGNOSTICS ▲
- .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.
