XSetFontPath(3) XLIB FUNCTIONS XSetFontPath(3)
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.
