Description

Obtains data sent from the connected endpoint of the socket that yous specified when you created your socket stream.

Read accepts the following parameters:

• Buf is a pointer to the buffer to receive the incoming data.
• Count is the length (in bytes) of the buffer pointed by Buf, which is also the maximum length of the requested data that Read returns.

Exceptions

A call to Read can raise any of the following exceptions:

Exception	Exception.Message	Scenarios
ESocketError	Network socket error: <error message> (<error code>), on API 'ioctlsocket'	The operating system reported an error while reading the length of the received data. This may happen if you provide -1 as the value of Count or if you provide the Bytes parameter in your call. For more information, see the following documentation for the operating system where your application was running: Windows: ioctlsocket function (MSDN) OS X: ioctl (OS X Man Pages) iOS: ioctl (iOS Manual Pages) Android: ioctl (Linux Programmer's Manual)
	Network socket error: <error message> (<error code>), on API 'recv'	The operating system reported an error while receiving data from your socket. This may happen if you provide a value other than -1 as the value of Count. For more information, see the following documentation for the operating system where your application was running: Windows: recv function (MSDN) OS X: recv (OS X Man Pages) iOS: recv (iOS Manual Pages) Android: recv (Linux Programmer's Manual)
