phoneGetMessage

The phoneGetMessage function returns the next TAPI message that is queued for delivery to an application that is using the Event Handle notification mechanism (see phoneInitializeEx for further details).

LONG phoneGetMessage(

HPHONEAPP hPhoneApp,

LPPHONEMESSAGE lpMessage,

DWORD dwTimeout

);

Parameters

hPhoneApp

The handle returned by phoneInitializeEx. The application must have set the PHONEINITIALIZEEXOPTION_USEEVENT option in the dwOptions field of the PHONEINITIALIZEEXPARAMS structure.

lpMessage

A pointer to a PHONEMESSAGE structure. Upon successful return from this function, the structure will contain the next message which had been queued for delivery to the application.

dwTimeout

The time-out interval, in milliseconds. The function returns if the interval elapses, even if no message can be returned. If dwTimeout is zero, the function checks for a queued message and returns immediately. If dwTimeout is INFINITE, the function's time-out interval never elapses.

Return Values

Returns zero if the request is successful or a negative error number if an error has occurred. Possible return values are:

PHONEERR_INVALAPPHANDLE, PHONEERR_OPERATIONFAILED, PHONEERR_INVALPOINTER, PHONEERR_NOMEM.

Remarks

If this function has been called with a non-zero timeout and the application calls phoneShutdown on another thread, this function will return immediately with PHONEERR_INVALAPPHANDLE.

If the timeout expires (or was zero) and no message could be fetched from the queue, the function returns with the error PHONEERR_OPERATIONFAILED.
