.SH DESCRIPTION

The

.ZN 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

.ZN XmbLookupString

or

.ZN 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.

.LP

The specific input method to which this call will be routed

is identified on the basis of the current locale. 

.ZN XOpenIM

will identify a default input method corresponding to the

current locale.

That default can be modified using 

.ZN XSetLocaleModifiers

for the input method modifier.

.LP

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.

.LP

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.

.LP

The res_name and res_class arguments are not assumed to exist beyond

the call to

.ZN XOpenIM .

The specified resource database is assumed to exist for the lifetime

of the input method.

.LP

.ZN XOpenIM

returns NULL if no input method could be opened.

.LP

The

.ZN XCloseIM

function closes the specified input method.

.LP

The

.ZN 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.

.LP

The

.ZN 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.

.LP

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

.ZN XGetIMValues

allocates memory to store the actual data,

and the client is responsible for freeing this data by calling

.ZN XFree

with the returned pointer.

.LP

The

.ZN XDisplayOfIM

function returns the display associated with the specified input method.

.LP

The

.ZN XLocaleOfIM

function returns the locale associated with the specified input method.

.LP

The

.ZN 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.

.LP

The function returns 

.ZN True

if it succeeds; otherwise, it returns 

.ZN False .

.LP

The

.ZN XUnregisterIMInstantiateCallback

function removes an input method instantiation callback previously

registered.

The function returns

.ZN True

if it succeeds; otherwise, it returns 

.ZN False .
