In computing, a computer program or subroutine is called reentrant if it can be interrupted in the middle of its execution and then safely called again before its previous invocations complete executing. The interruption could be caused by an internal action such as a jump or call or by an external action such as a hardware interrupt or signal. Once the reentered invocation completes, the previous invocations will resume correct execution.
