Routine Description:
|
|
|
|
This routine returns address information about a specific service.

|
Arguments:
|
|
|
|
lpServiceType - pointer to the GUID for the service type
|
|
|
|
lpServiceName - unique string representing the service name.
|
|
|
|
lpdwProtocols - a zero terminated array of protocol ids. This parameter
|
|
is optional; if lpdwProtocols is NULL, information on all available
|
|
Protocols is returned
|
|
|
|
dwResolution - can be one of the following values:RES_SERVICE
|
|
|
|
lpCsAddrBuffer - on return, will be filled with CSADDR_INFO structures
|
|
|
|
lpdwBufferLength - on input, the number of bytes contained in the buffer
|
|
pointed to by lpCsAddrBuffer. On output, the minimum number of bytes
|
|
to pass for the lpCsAddrBuffer to retrieve all the requested info
|
|
|
|
lpAliasBuffer - not used
|
|
|
|
lpdwAliasBufferLength - not used
|
|

|

|

|
The number of CSADDR_INFO structures returned, or SOCKET_ERROR (-1) if

the lpCsAddrBuffer is too small. Use GetLastError() to retrieve the
|
|
