ReceiveFrom Method

Reads a portion of data received via a specific channel into a string.

Syntax

QString ReceiveFrom(int iChannel);

Remarks

Use this method to read out a piece of data received from the server into a string. Use the Channel parameter to specify the channel that you would like to read from (0 for stdout, 1 for stderr).

Note that in synchronous mode this method may block in the absence of any inbound data until the next piece of data is received from the server. Use Poll to check if there is any data in the connection that is immediately available for reading.

In asynchronous mode a good time to call this method is upon receiving a read notification in DataReceived event handler. When working in asynchronous mode, this call returns immediately.

Error Handling

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.
