     cells of a pattern object

SYNOPSIS
     #include <Tt/tt_c.h>
     Tt_status tt_pattern_user_set(Tt_pattern p,
                                   int key,
                                   void *v);

DESCRIPTION
     The tt_pattern_user_set() function stores information in the
     user  data  cells  associated  with  the  specified  pattern
     object.

     The p argument is a unique handle  for  a  message  pattern.
     This   handle  is  returned  after  tt_pattern_create(3)  is
     called.  The key argument is the specified user  data  cell.
     The  value  for  each data cell must be unique for this pat-
     tern.  The v argument is the data cell, a piece of arbitrary
     user data that can hold a void *.

RETURN VALUE
     Upon successful completion, the tt_pattern_user_set()  func-
     tion  returns the status of the operation as one of the fol-
     lowing Tt_status values:

        TT_OK   The operation completed successfully.

        TT_ERR_NOMP
                The ttsession(1) process is not running  and  the
                ToolTalk service cannot restart it.

        TT_ERR_POINTER
                The pointer passed does not point to an object of
                the correct type for this operation.
