I don't understand what you are attempting nor what error you think you might be experiencing.

Ironically, the only part of your post that I decipher are the parameters that you find strange.

Your message queue is 4140 bytes long, the number of messages on the queue is zero, and the time of the last message send is... well, you never have sent a message to this queue.

Why is that strange? What is pushing and pulling? Do you mean push/pop as with a stack? How do you think you can do that? What does disabled mean? How do you approach a queue?

tt_message_disposition(library call)									      tt_message_disposition(library call)

NAME
tt_message_disposition -- retrieve the disposition attribute from a message SYNOPSIS
#include <Tt/tt_c.h> Tt_disposition tt_message_disposition( Tt_message m); DESCRIPTION
The tt_message_disposition function retrieves the disposition attribute from the specified message. The m argument is the opaque handle for the message involved in this operation. RETURN VALUE
Upon successful completion, the tt_message_disposition function returns a value that indicates whether an instance of the receiving process should be started to receive the message immediately, or whether the message is to be queued until the receiving process is started at a later time. The tt_message_disposition function returns one of the following Tt_disposition values: TT_DISCARD There is no receiver for this message. The message will be returned to the sender with the Tt_status field containing TT_FAILED. TT_QUEUE Queue the message until a process of the proper ptype receives the message. TT_START Attempt to start a process of the proper ptype if none is running. TT_QUEUE+TT_START Queue the message and attempt to start a process of the proper ptype if none is running. The application can use tt_int_error(3) to extract one of the following Tt_status values from the Tt_disposition integer: 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.
