lineGetAddressStatusA function

-description

The lineGetAddressStatus function allows an application to query the specified address for its current status.

-parameters

-param hLine

Handle to the open line device.

-param dwAddressID

Address on the given open line device. This is the address to be queried. An address identifier is permanently associated with an address; the identifier remains constant across operating system upgrades.

-param lpAddressStatus

Pointer to a variably sized data structure of type LINEADDRESSSTATUS. Prior to calling lineGetAddressStatus, the application must set the dwTotalSize member of this structure to indicate the amount of memory available to TAPI for returning information.

Note  If the size parameters in the structure are not correct, there is a possibility that data could get overwritten. For more information on setting structure sizes, see the memory allocation topic.
 

-returns

Returns zero if the request succeeds or a negative error number if an error occurs. Possible return values are:

LINEERR_INVALADDRESSID, LINEERR_RESOURCEUNAVAIL, LINEERR_INVALLINEHANDLE, LINEERR_STRUCTURETOOSMALL, LINEERR_INVALPOINTER, LINEERR_UNINITIALIZED, LINEERR_NOMEM, LINEERR_OPERATIONUNAVAIL, LINEERR_OPERATIONFAILED.

-remarks

Note

The tapi.h header defines lineGetAddressStatus as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
