  • Article

Contains the result of a call to an asynchronous function. This structure is used with InternetStatusCallback.

Syntax

typedef struct {
  DWORD_PTR dwResult;
  DWORD     dwError;
} INTERNET_ASYNC_RESULT, *LPINTERNET_ASYNC_RESULT;

Members

dwResult

Result. This parameter can be an HINTERNET handle, unsigned long integer, or Boolean return code from an asynchronous function.

dwError

Error code, if dwResult indicates that the function failed. If the operation succeeded, this member usually contains ERROR_SUCCESS.

Remarks

The value of dwResult is determined by the value of
dwInternetStatus in the status callback function.

Value of dwInternetStatus Value of dwResult
INTERNET_STATUS_HANDLE_CREATED Pointer to the HINTERNET handle
INTERNET_STATUS_REQUEST_COMPLETE Boolean return code from the asynchronous function.
