The Windows Sockets WSAEnumNameSpaceProviders
function retrieves information about available name spaces.
INT WSAAPI WSAEnumNameSpaceProviders (
| LPDWORD lpdwBufferLength,
| LPWSANAMESPACE_INFO lpnspBuffer
[in/out] On input, the number of bytes contained in the buffer pointed to by lpnspBuffer
. On output (if the function fails, and the error is WSAEFAULT), the minimum
number of bytes to pass for the lpnspBuffer
to retrieve all the requested information. The passed-in buffer must be
sufficient to hold all of the name space information.
[out] A buffer which is filled with WSANAMESPACE_INFO
structuresdescribed below. The returned structures are located consecutively
at the head of the buffer. Variable sized information referenced by pointers in
the structures point to locations within the buffer located between the end of
the fixed sized structures and the end of the buffer. The number of structures
filled in is the return value of WSAEnumNameSpaceProviders
WSAEnumNameSpaceProviders returns the number of WSANAMESPACE_INFO
structures copied into lpnspBuffer
. Otherwise, the value SOCKET_ERROR is returned, and a specific error number
may be retrieved by calling WSAGetLastError
||the buffer length was too small to receive all the relevant WSANAMESPACE_INFO structures and associated information. Pass in a buffer at least as large as
the value returned in lpdwBufferLength.
||The Windows Sockets 2 DLL has not been initialized. The application must first
call WSAStartup before calling any Windows Sockets functions.
