NAME

       tt_message_receive -- receive a message

SYNOPSIS

       #include <Tt/tt_c.h>
       Tt_message tt_message_receive(void)

DESCRIPTION

       The  tt_message_receive	function  returns a handle for the next message queued to be delivered to the process and also runs any message or
       pattern callbacks applicable to the queued message.

       If the return value of tt_message_status(3) for this message is TT_WRN_START_MESSAGE, the ToolTalk service started the process  to  deliver
       the queued message; the process must reply to this message.  If the return value of tt_message_receive is zero, no message is available.

RETURN VALUE

       Upon  successful  completion,  the  tt_message_receive  function  returns  the  handle  for  the  message  object.  The application can use
       tt_ptr_error(3) to extract one of the following Tt_status values from the returned handle:

       TT_OK	 The operation completed successfully.

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

APPLICATION USAGE

       A zero value can occur if a message or pattern callback processes the message.  It can also occur if the interval is too long  between  the
       time  the  file	descriptor became active and the tt_message_receive call was made.  In the latter case, the ToolTalk service will time out
       and offer the message to another process.

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