Receive an Exact Number of Bytes into a BinData
See more Socket/SSL/TLS Examples
Demonstrates Socket.ReceiveBdN, which receives exactly the requested number of bytes and appends them to a BinData, continuing until the full count is satisfied.
Background. Inactivity is controlled by
MaxReadIdleMs: the call fails if incoming bytes halt for longer than MaxReadIdleMs milliseconds before the full amount is received. A single receive returns only what is currently available, whereas this counted receive waits for an exact number of bytes.Chilkat B4X Downloads
