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.

use strict;

my $socket = Chilkat2::Socket->new;

# Connect to the server using TLS.
my $bTls = 1;

    exit;

# MaxReadIdleMs controls the inactivity limit for receiving.  The ReceiveBdN call will fail if
# incoming bytes halt for longer than this many milliseconds before the full amount is received.

# Receive exactly the requested number of bytes, appending them to a BinData.  The method continues
# receiving until the full count is satisfied or a failure occurs.
