TAPI Error Values

TAPIERR_INVALDESTADDRESS

The pointer to the destination address is not valid, is NULL, or the destination address string is too long.

TAPIERR_INVALPOINTER

The pointer does not reference a valid memory location. One or more of the pointers lpszDestAddress, lpszAppName, lpszCalledParty, or lpszComment have been specified but are invalid.

TAPIERR_NOREQUESTRECIPIENT

No recipient application is available to handle the request. The user should start the recipient application and try again.

TAPIERR_REQUESTFAILED

The request failed for unspecified reasons.

TAPIERR_REQUESTQUEUEFULL

A recipient application is active, but the request queue is full or there is insufficient memory to expand the queue. The application can try again later.

Any other TAPIERR_ values are nonfunctional in Win32-based applications and must not be used.
