IsWritable Property  
 

Return if data can be sent to the server without blocking.

Syntax

object.IsWritable

Remarks

The IsWritable property returns True if data can be written without blocking. For non-blocking connections, this property can be checked before the application attempts to send data to the server, preventing an error.

If the IsWritable property returns False, this means that the application cannot write to the socket at that time. However, if the property returns True, this does not guarantee that you will be able to send data without an error. The next operation may result in an stErrorOperationWouldBlock or stErrorOperationInProgress error. The application must treat these errors as recoverable, and should be prepared to retry operations that result in them.
