    NAME
         ttdt_Revert - request a ToolTalk client to revert a file
    
    SYNOPSIS
         #include <Tt/tttk.h>
         Tt_status ttdt_Revert(Tt_message context,
                               const char *pathname,
                               Tt_scope the_scope,
                               XtAppContext app2run,
                               int ms_timeout);
    
    DESCRIPTION
         The ttdt_Revert() function sends a  Revert  request  in  the
         the_scope  argument  and  waits  for  the  reply.   A Revert
         request asks the handling ToolTalk  client  to  discard  any
         changes pending on pathname.
    
         The context argument describes the environment to  use.   If
         context  is  not  zero,  messages  created  by ttdt_Revert()
         inherit from context all contexts whose slotname begins with
         the characters ENV_.
    
         The the_scope argument identifies the scope of the  request.
         If  the_scope is TT_SCOPE_NONE, ttdt_Revert() tries TT_BOTH,
         and falls back to TT_FILE_IN_SESSION if,  for  example,  the
         ToolTalk database server is not installed on the file server
         that owns pathname.
    
         The ttdt_Revert() function passes app2run and ms_timeout  to
         tttk_block_while(3),  blocking  on  the  reply  to  the Save
         request it sends.
    
    RETURN VALUE
         Upon  successful  completion,  the  ttdt_Revert()   function
         returns  the status of the operation as one of the following
         Tt_status values:
    
            TT_OK   The sent request received  an  affirmative  reply
                    within ms_timeout milliseconds.
    
            TT_DESKTOP_ETIMEDOUT
                    No reply  was  received  within  ms_timeout  mil-
                    liseconds.
    
            TT_DESKTOP_EPROTO
                    The request was failed, but the handler  set  the
                    tt_message_status()   of  the  failure  reply  to
                    TT_OK, instead of a specific error status.
    
            TT_ERR_DBAVAIL
                    The ToolTalk service could not access  the  Tool-
                    Talk database needed for this operation.
    
            TT_ERR_DBEXIST
                    The ToolTalk service could not access the  speci-
                    fied ToolTalk database in the expected place.
    
            TT_ERR_NOMEM
                    There is insufficient memory available to perform
                    the function.
    
            TT_ERR_NOMP
                    The ttsession(1) process is not running  and  the
                    ToolTalk service cannot restart it.
    
            TT_ERR_OVERFLOW
                    The ToolTalk service  has  more  active  messages
                    than  it  can  handle.   (The  maximum  number of
                    active messages is implementation  specific,  but
                    is at least 2000.)
    
            TT_ERR_POINTER
                    The pathname argument was NULL or was a  ToolTalk
                    error pointer.
    
            TT_ERR_PROCID
                    The specified process identifier is out  of  date
                    or invalid.
