---

Writes data to an open Internet file.

Syntax

BOOL InternetWriteFile(
    IN HINTERNET hFile,
    IN LPCVOID lpBuffer,
    IN DWORD dwNumberOfBytesToWrite,
    OUT LPDWORD lpdwNumberOfBytesWritten
);

Parameters

hFile

Valid HINTERNET handle returned from a previous call to FtpOpenFile or an HINTERNET handle sent by HttpSendRequestEx.

lpBuffer

Address of a buffer that contains the data to be written to the file.

dwNumberOfBytesToWrite

Unsigned long integer value that contains the number of bytes to write to the file.

lpdwNumberOfBytesWritten

Address of an unsigned long integer variable that receives the number of bytes written to the buffer. InternetWriteFile sets this value to zero before doing any work or error checking.
