# GetUniDirectionalAdapterInfo(3w)

## NAME

**GetUniDirectionalAdapterInfo** (IPHLPAPI.@)

## SYNOPSIS

DWORD GetUniDirectionalAdapterInfo\
  (\
   PIP\_UNIDIRECTIONAL\_ADAPTER\_ADDRESS *pIPIfInfo*,\
   PULONG                             *dwOutBufLen*\
  )

## DESCRIPTION

This is a Win98-only function to get information on **"unidirectional"** adapters. Since this is pretty nonsensical in other contexts, it never returns anything.

## PARAMS

*pIPIfInfo* **\[Out\]**  buffer for adapter infos.

*dwOutBufLen* **\[Out\]**  length of the output buffer.

## RETURNS

**Success:** **NO\_ERROR**

**Failure:** error code from Winerror.h.

## FIXME

Stub, returns **ERROR\_NOT\_SUPPORTED**.

## IMPLEMENTATION

Declared in **"iphlpapi.h"**.

Implemented in **"dlls/iphlpapi/iphlpapi\_main.c"**.

Debug channel **"iphlpapi"**.
