XSetICValues(3X11) XLIB FUNCTIONS XSetICValues(3X11)NAME
XSetICValues, XGetICValues - set and obtain XIC values
SYNTAX
char * XSetICValues(ic, ...)
XIC ic;
char * XGetICValues(ic, ...)
XIC ic;
ARGUMENTS
ic Specifies the input context.
... Specifies the variable length argument list to
set or get XIC values.
DESCRIPTION
The XSetICValues function returns NULL if no error
occurred; otherwise, it returns the name of the first
argument that could not be set. An argument might not be
set for any of the following reasons:
o The argument is read-only (for example,
XNFilterEvents).
o The argument name is not recognized.
o An implementation-dependent error occurs.
Each value to be set must be an appropriate datum, match-
ing the data type imposed by the semantics of the argu-
ment.
The XSetICValues can generate BadAtom, BadColor,
BadCursor, BadPixmap, and BadWindow errors.
The XGetICValues function returns NULL if no error
occurred; otherwise, it returns the name of the first
argument that could not be obtained. An argument could
not be obtained for any of the following reasons:
o The argument name is not recognized.
o The input method encountered an implementation-depen-
dent error.
Each IC attribute value argument (following a name) must
point to a location where the IC value is to be stored.
That is, if the IC value is of type T, the argument must
be of type T*. If T itself is a pointer type, then XGet-
ICValues allocates memory to store the actual data, and
the client is responsible for freeing this data by calling
XFree with the returned pointer. The exception to this
rule is for an IC value of type XNVaNestedList (for

preedit and status attributes). In this case, the argu-
ment must also be of type XVaNestedList. Then, the rule
of changing type T to T* and freeing the allocated data
applies to each element of the nested list.
DIAGNOSTICS
BadAtom A value for an Atom argument does not name a
defined Atom.
BadColor A value for a Colormap argument does not name a
defined Colormap.
BadCursor A value for a Cursor argument does not name a
defined Cursor.
BadPixmap A value for a Pixmap argument does not name a
defined Pixmap.
BadWindow A value for a Window argument does not name a
defined Window.
