WpEnumProviders

DWORD WpEnumProviders(
	[in, out]		LPDWORD		pdwProvidersBufLen
	[out]		LPWPPROVINFO	pProvidersBuffer
	[out]		LPDWORD		pdwNumProviders
	);

Retrieves the list of all currently registered providers.

• Returns NO_ERROR if successful. Otherwise, returns an error code, which may be one of the following:

  E_INVALIDARG

  E_OUTOFMEMORY

  WEBPOST_ERROR_INIT_FAILED

  WEBPOST_ERROR_PROV_CORRUPT

  WEBPOST_ERROR_ENUM_PROVS

  More information about these error codes can be found in Appendix B, Error Codes.

pdwProvidersBufLen

Size, in bytes, of pProvidersBuffer. On return, contains the actual number of bytes used in pProvidersBuffer. If pProvidersBuffer is NULL or too small to hold all the providers, this parameter shows the necessary size of the buffer to allocate.

pProvidersBuffer

Receives an array of WPPROVINFO structures.

pdwNumProviders

Number of providers. This value is set whether or not pProvidersBuffer is NULL or points to a large enough buffer.

Examples
C/C=++

{
	HRESULT hResult = NOERROR;
	DWORD BufLen;
	DWORD Num;
	
	hResult = WpEnumProviders(&BufLen, NULL, &Num);	
}
