       - open, close, and obtain input method information

SYNTAX
       XIM XOpenIM(Display *display, XrmDatabase db, char *res_name, char
              *res_class);

       Status XCloseIM(XIM im);

       char *XSetIMValues(XIM im, ...);

       char *XGetIMValues(XIM im, ...);

       Display *XDisplayOfIM(XIM im);

       char *XLocaleOfIM(XIM im);

       Bool XRegisterIMInstantiateCallback(Display *display, XrmDatabase db,
              char *res_name, char *res_class, XIDProc callback, XPointer
              client_data);

       Bool XUnregisterIMInstantiateCallback(Display *display, XrmDatabase db,
              char *res_name, char *res_class, XIDProc callback, XPointer
              client_data);

ARGUMENTS
       callback  Specifies a pointer to the input method instantiate 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 application.

       ...       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 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 cur-
       rent at the time the input method is opened.

       The specific input method to which this call will be routed is identi-
       fied 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 XSetLocaleModifiers for the input method modi-
       fier.

       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 Character
       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 specified input method.  It
       returns NULL if it succeeds; otherwise, 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 cor-
       rectly.

       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 argument 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 responsible for freeing this data by calling XFree with
       the returned pointer.

       The XDisplayOfIM function returns the display associated with the spec-
       ified input method.

       The XLocaleOfIM function returns the locale associated with the speci-
       fied 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.
