NAME
XSetFontPath, XGetFontPath, XFreeFontPath - set, get, or free the font search
path
SYNTAX
int XSetFontPath(Display *
display, char **
directories, int
ndirs);
char
**XGetFontPath(Display * display, int *npaths_return);
int
XFreeFontPath(char ** list);
ARGUMENTS
- directories
- 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
- Specifies the connection to the X server.
- list
- Specifies the array of strings you want to free.
- ndirs
- Specifies the number of directories in the path.
- npaths_return
- Returns the number of strings in the font path array.
DESCRIPTION
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.
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.
DIAGNOSTICS
- 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.
