ARGUMENTS
callback Specifies a pointer to the input method instan-
tiate callback.
client_data
Specifies the additional client data.
db Specifies a pointer to the resource database.
display Specifies the connection to the X server.
im Specifies the input method.
res_class Specifies the full class name of the application.
res_name Specifies the full resource name of the applica-
tion.
... Specifies the variable length argument list to set
or get XIM values.
DESCRIPTION
The XOpenIM function opens an input method, matching the
current locale and modifiers specification. Current locale
XFree86 Version 4.5.0 1
XOpenIM(3X11) XLIB FUNCTIONS XOpenIM(3X11)
and modifiers are bound to the input method at opening time.
The locale associated with an input method cannot be changed
dynamically. This implies that the strings returned by
XmbLookupString or XwcLookupString, for any input context
affiliated with a given input method will be encoded in the
locale current at the time the input method is opened.
The specific input method to which this call will be routed
is identified on the basis of the current locale. XOpenIM
will identify a default input method corresponding to the
current locale. That default can be modified using XSetLo-
caleModifiers for the input method modifier.
The db argument is the resource database to be used by the
input method for looking up resources that are private to
the input method. It is not intended that this database be
used to look up values that can be set as IC values in an
input context. If db is NULL, no database is passed to the
input method.
The res_name and res_class arguments specify the resource
name and class of the application. They are intended to be
used as prefixes by the input method when looking up
resources that are common to all input contexts that may be
created for this input method. The characters used for
resource names and classes must be in the X Portable Charac-
ter Set. The resources looked up are not fully specified if
res_name or res_class is NULL.
The res_name and res_class arguments are not assumed to
exist beyond the call to XOpenIM. The specified resource
database is assumed to exist for the lifetime of the input
method.
XOpenIM returns NULL if no input method could be opened.
The XCloseIM function closes the specified input method.
The XSetIMValues function presents a variable argument list
programming interface for setting attributes of the speci-
fied input method. It returns NULL if it succeeds; other-
wise, it returns the name of the first argument that could
not be set. Xlib does not attempt to set arguments from the
supplied list that follow the failed argument; all arguments
in the list preceding the failed argument have been set
correctly.
The XGetIMValues function presents a variable argument list
programming interface for querying properties or features of
the specified input method. This function returns NULL if it
succeeds; otherwise, it returns the name of the first argu-
ment that could not be obtained.

Each XIM value argument (following a name) must point to a
location where the XIM value is to be stored. That is, if
the XIM value is of type T, the argument must be of type T*.
If T itself is a pointer type, then XGetIMValues allocates
memory to store the actual data, and the client is responsi-
ble for freeing this data by calling XFree with the returned
pointer.
The XDisplayOfIM function returns the display associated
with the specified input method.
The XLocaleOfIM function returns the locale associated with
the specified input method.
The XRegisterIMInstantiateCallback function registers a
callback to be invoked whenever a new input method becomes
available for the specified display that matches the current
locale and modifiers.
The function returns True
if it succeeds; otherwise, it returns False.
The XUnregisterIMInstantiateCallback function removes an
input method instantiation callback previously registered.
The function returns True if it succeeds; otherwise, it
returns False.
