NAME
     tt_default_ptype - retrieve the current default ptype

SYNOPSIS
     #include <Tt/tt_c.h>
     char *tt_default_ptype(void);

DESCRIPTION
     The  tt_default_ptype()  function  retrieves   the   current
     default ptype.

     When the application declares a ptype, the ptype becomes the
     default.

RETURN VALUE
     Upon successful completion, the tt_default_ptype()  function
     returns  a pointer to a character string that uniquely iden-
     tifies the current default process type.  If the pointer  is
     NULL,  no  default  ptype  is  set.  The application can use
     tt_ptr_error(3) to extract one of  the  following  Tt_status
     values from the returned pointer:

        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_PROCID
                The current default process identifier is out  of
                date or invalid.

APPLICATION USAGE
     The application should  use  tt_free(3)  to  free  any  data
     stored in the address returned by the ToolTalk API.
