GetNetworkParams

The GetNetworkParams function retreives network parameters for the local computer.

DWORD GetNetworkParams(
  PFIXED_INFO pFixedInfo,   // pointer to buffer to receive data
  PULONG pOutBufLen         // size of buffer
);

Parameters

pFixedInfo: Pointer to a FIXED_INFO structure that, on successful return, contains the netword parameters for the local computer.
pOutBufLen: Pointer to a ULONG variable that specifies the size of the FIXED_INFO structure. If this size is insufficient to hold the information, GetNetworkParams fills in this variable with the required size, and returns an error code of ERROR_BUFFER_OVERFLOW.

Return Values

If the function succeeds, the return value is ERROR_SUCCESS.

If the function fails, the return value is one of the following error codes.

Value	Meaning
ERROR_BUFFER_OVERFLOW	The buffer size indicated by the pOutBufLen parameter is too small to hold the adapter information. The pOutBufLen parameter points to the required size.
ERROR_INVALID_PARAMETER	The pOutBufLen parameter is NULL, or the calling process does not have read/write access to the memory pointed to by pOutBufLen, or the calling process does not have write access to the memory pointed to by the pAdapterInfo parameter.
ERROR_NO_DATA	No adapter information exists for the local computer.
ERROR_NOT_SUPPORTED	GetNetworkParams is not supported by the operating system running on the local computer.
Other	If the function fails, use FormatMessage to obtain the message string for the returned error.
