This function reads data from a handle opened by the InternetOpenUrl, FtpOpenFile, or HttpOpenRequest function.

Syntax

  HINTERNET hFile, 
  LPVOID lpBuffer, 
  DWORD dwNumberOfBytesToRead, 
  LPDWORD lpdwNumberOfBytesRead
);

Parameters

  • hFile
    [in ] Valid handle returned from a previous call to InternetOpenUrl, FtpOpenFile, or HttpOpenRequest.

  • dwNumberOfBytesToRead
    [in] Specifies the number of bytes to read.
