tt_default_ptype(3)    C LIBRARY FUNCTIONS    tt_default_ptype(3)

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		The current default process identifier is out  of
		date or	invalid.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