WNetGetProviderName info Overview Group

The WNetGetProviderName function obtains the provider name for a specific type of network.

DWORD WNetGetProviderName(

DWORD dwNetType,	// specifies network type
LPTSTR lpProvider,	// pointer to buffer to receive provider name
LPDWORD lpBufferSize	// size of buffer
);

Parameters

dwNetType: Specifies the network type unique to the network. If two networks claim the same type, the function returns the name of the type loaded first. Only the high word of the network type is used. If a network reports a subtype in the low word, it is ignored.
lpProvider: Pointer to a buffer in which to return the provider name.
lpBufferSize: The size, in characters, of the buffer passed to the function call. If the result is WN_MORE_DATA, lpBufferSize contains the buffer size required (in characters) to hold the provider name.
Windows 95: Size is in bytes, not characters. Also, the buffer must be at least 1 byte long.

If the function succeeds, the return value is WN_SUCCESS. If the function fails, one of the following errors will occur:

Value	Meaning
WN_MORE_DATA	The buffer is too small to hold the provider name.
WN_NO_NETWORK	The network is not present.
WN_BAD_POINTER	lpProvider or lpBufferSize is invalid.
