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

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 ser‐
vice cannot restart it.
TT_ERR_POINTER
