Response structure from the function
The function returns the following structure:
WORD wNrOfInstances
where:
wNrOfInstances The value of the update use count for the MM application at the
end of the function handling. It contains the number of times a
remote PC has connected over the same communication
medium. E.g. the first time the MM_C_START_MM function is
called, it contains the value 1.
Error codes returned
MM_E_NOERROR
MM_E_OPEN_CLOSE_FAILED

3.2.2 MM_C_STOP_MM
Purpose
Indicates the CCU that the remote controller no longer requires updates from the MM applica-
tion inside the CCU. After receiving this function the CCU decrements the update use count.
As long as the update use count is still greater than zero, the CCU remains sending the
update notifications to the remote controller.
A call to this function when the update use count is already zero will keep the use count to
zero and nothing shall happen.
When the use count reaches zero then the microphone management application inside the
CCU returns to its stand-alone operation. This return involves a change in the following
settings of the MM-application:
Setting Parameter Section Destination of change
wOperationMode 3.2.5 When the operation mode is
MM_C_OPERATOR_WITH_REQ_LIST or
MM_C_OPERATOR_WITH_COMMENT_LIST the
mode will be changed to
MM_C_DELEGATE_WITH_REQ_LIST. All other
modes will remain active.
wActiveMics 3.2.6 When the number of active microphones is 3, this will
be extended to 4. This implies also changes of the SPK
and RTS lists.
bAllowMicroOff 3.2.7 This value is set to TRUE. Note that this value is only
used in the modes
MM_C_OPERATOR_WITH_REQ_LIST and
MM_C_OPERATOR_WITH_COMMENT_LIST.
All other MM-settings remain active while functioning in stand-alone mode.
Note that: Upon communication lost this function will be activated, if
MM_C_START_MM was activated. The activation of this function is repeated
till the update use count becomes zero.
Parameter structure for the function
The function has no additional parameters.
Response structure from the function
The function has the same response structure as the remote function MM_C_START_MM
(section 3.2.1).
