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 applica-
tion.
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 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
XSetLocaleModifiers 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 Char-
acter Set. The resources looked up are not fully speci-
fied 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 correctly.
The XGetIMValues function presents a variable argument
list programming interface for querying properties or fea-
tures 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 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 cur-
rent 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.
