Routine Description:
|
|
|
|
Writes a block of data for an outstanding HTTP request
|
|
|
|
Assumes: 1. this function can only be called from InternetWriteFile() which
|
|
globally validates parameters for all Internet data write
|
|
functions
|
|
|
|
2. That we the caller has called HttpBeginSendRequest but not HttpEndSendRequest
|
|
|
|
Arguments:
|
|
|
|
hRequest - an open HTTP request handle returned by
|
|
HttpOpenRequest()
|
|
|
|
lpBuffer - pointer to the buffer to receive the data
|
|
|
|
dwNumberOfBytesToWrite - number of bytes to write from user's buffer
|
|
|
|
lpdwNumberOfBytesWritten - number of bytes actually written
|
|
|
|
dwSocketFlags - controlling socket operation
|
|
|
|
|
|
Return Value:
|
|
|
|
TRUE - The data was written successfully. lpdwNumberOfBytesRead points to the
|
|
number of BYTEs actually read. This value will be set to zero
|
|
when the transfer has completed.
|
|
|
|
FALSE - The operation failed. Error status is available by calling
|
|
GetLastError().
