ReturnExpressionPacket
✖
ReturnExpressionPacket
is a WSTP packet that contains the expression expr, the result of an EnterExpressionPacket evaluation.
Details
- A single EnterExpressionPacket may return multiple ReturnExpressionPacket expressions if a list of box expressions was sent.
- An EnterExpressionPacket might have no corresponding ReturnExpressionPacket if the expression suppresses its output.
- The final ReturnExpressionPacket in a given exchange is typically followed by an InputNamePacket.
