lineUnpark
The lineUnpark function retrieves the call parked at the specified address and returns a
call handle for it.
LONG lineUnpark(
HLINE hLine,
|
| DWORD dwAddressID,
|
| LPHCALL lphCall,
|
| LPCSTR lpszDestAddress
|
| );
|
|
Parameters
hLine
A handle to the open line device on which a call is to be unparked.
dwAddressID
The address on hLine at which the unpark is to be originated.
lphCall
A pointer to the location of type HCALL where the handle to the unparked call
is returned. This handle is unrelated to any other handle which might have been
previously associated with the retrieved call, such as the handle that might
have been associated with the call when it was originally parked. The
application will be the initial sole owner of this call.
lpszDestAddress
A pointer to a NULL-terminated character buffer that contains the address
where the call is parked. The address is in standard dialable address format.
Return Values
Returns a positive request ID if the function will be completed
asynchronously, or a negative error number if an error has occurred. The dwParam2 parameter of the corresponding LINE_REPLY message is zero if the function is
successful or it is a negative error number if an error has occurred. Possible
return values are:
LINEERR_INVALADDRESS, LINEERR_OPERATIONUNAVAIL, LINEERR_INVALADDRESSID,
LINEERR_OPERATIONFAILED, LINEERR_INVALLINEHANDLE, LINEERR_RESOURCEUNAVAIL,
LINEERR_INVALPOINTER, LINEERR_UNINITIALIZED, LINEERR_NOMEM.
