NAME
     tt_default_ptype - retrieve the current default ptype

SYNOPSIS
     #include <Tt/tt_c.h>

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                The current default process identifier is out of date or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