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. Set-
ting 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 implementa-
tion-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 implementa-
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 imple-
mentation-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.
