XSetFontPath(3) XLIB FUNCTIONS XSetFontPath(3)
XSetFontPath, XGetFontPath, XFreeFontPath - set, get, or free the font
int XSetFontPath(Display *display, char **directories, int ndirs);
char **XGetFontPath(Display *display, int *npaths_return);
int XFreeFontPath(char **list);
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.
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.
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.
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.
