       Status XCloseOM(XOM om);

       char *XSetOMValues(XOM om, ...);

       Display *XDisplayOfOM(XOM om);

       char *XLocaleOfOM(XOM om);

ARGUMENTS

       display   Specifies the connection to the X server.

       db        Specifies a pointer to the resource database.

       res_name  Specifies the full resource name of the application.

       res_class Specifies the full class name of the application.

       om        Specifies the output method.

       ...       Specifies the variable length argument list to set or get XOM values.

DESCRIPTION

       The XOpenOM function opens an output method matching  the  current  locale  and  modifiers
       specification.   The  current  locale  and  modifiers  are bound to the output method when
       XOpenOM is called.  The locale associated with an output method cannot be changed.

       The specific output method to which this call will be routed is identified on the basis of
       the  current  locale  and  modifiers.   XOpenOM  will  identify  a  default  output method
       corresponding  to  the   current   locale.    That   default   can   be   modified   using
       XSetLocaleModifiers to set the output method modifier.

       The  db  argument  is the resource database to be used by the output method for looking up
       resources that are private to the output method.  It is not intended that this database be
       used  to look up values that can be set as OC values in an output context.  If db is NULL,
       no database is passed to the output 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 output method when looking
       up resources that are common to all output contexts that may be created  for  this  output
       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 XOpenOM.
       The specified resource database is assumed to exist for the lifetime of the output method.

       XOpenOM returns NULL if no output method could be opened.

       The XCloseOM function closes the specified output method.

       The XSetOMValues function presents a variable  argument  list  programming  interface  for
       setting properties or features of the specified output method.  This function 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.

       No standard arguments are currently defined by Xlib.

       The XGetOMValues function presents a variable  argument  list  programming  interface  for
       querying  properties  or  features  of the specified output method.  This function returns
       NULL if it succeeds; otherwise, it returns the name of the first argument that  could  not
       be obtained.

       The XDisplayOfOM function returns the display associated with the specified output method.

       The XLocaleOfOM returns the locale associated with the specified output method.
