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 de-
fault 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 ex-
ist 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 and frees the
memory pointed to by the im argument.
The XSetIMValues function presents a variable argument list programming
interface for setting attributes of the specified input method. It re-
turns 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 features of the specified input
method. This function returns NULL if it succeeds; otherwise, it re-
turns 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.
