WpGetErrorString

DWORD WpGetErrorString(
	[in]		UINT		uErrCode
	[in, out]		LPTSTR	szOutputBuf
	[in, out]		DWORD *	pdwBuflen
	);

Provides a textual explanation of the specified error code.

uErrCode
The error code to translate.
szOutputBuf
The error message as NULL-terminated string. If NULL or not large enough, then use the value returned in pdwBufLen to allocate the necessary buffer.
pdwBufLen
On entry, the size of buffer provided. On return, the required buffer size in bytes.

The error code is first looked up in Web Publishing's error message table, then in the Win32® system table. If the error code cannot be translated, the function returns E_FAIL and the buffer is filled with an "Unknown Error" message.

Examples
C/C=++ 

{
	HRESULT hResult = NOERROR;
	DWORD BufLen;

	hResult = WpGetErrorString(0, NULL, &BufLen);
}
