The XOpenIM(3) 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 the strings returned by XmbLookupString(3) or XwcLookupString(3), for any input context affiliated with a given input method, will be encoded in the locale current at the time 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(3) will identify a default input method corresponding to the current locale. That default can be modified using XSetLocaleModifiers(3) 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 data base 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 can 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(3). The specified resource database is assumed to exist for the lifetime of the input method.
XOpenIM(3) returns NULL if no input method could be opened.
The XCloseIM(3) function closes the specified input method.
The XGetIMValues(3) 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.
Only one standard argument is defined by Xlib: XNQueryInputStyle, which must be used to query about input styles supported by the input method.
A client should always query the input method to determine which styles are supported. The client should then find an input style it is capable of supporting.
If the client cannot find an input style that it can support it should negotiate with the user the continuation of the program (exit, choose another input method, and so on).
The argument value must be a pointer to a location where the returned value will be stored. The returned value is a pointer to a structure of type XIMStyles. Clients are responsible for freeing the XIMStyles data structure. To do so, use XFree(3).
The XDisplayOfIM(3) function returns the display associated with the specified input method.
The XLocaleOfIM(3) returns the locale associated with the specified input method.
