Initializing help system before first use

handleintr

Purpose
Install or remove a handler for interruption.
This function installs or removes a function that is invoked periodically by the solver to check whether R has requested an interruption. If such a request is detected then the solver will interrupt itself at the next opportunitiy and will return gracefully to R.
Synopsis
handleintr(prob, set)
Arguments
prob 
The problem into which the handler should be installed or from which it should be removed.
set 
TRUE to install a handler, FALSE to remove it.
Return value
Always returns 0 (zero).
Further information
Attention! Checking for an interrupt may result in performance degradation, that is why interrupt checking is not enabled by default. Do not call this function while a solve is in progress, i.e., do not call it from a callback.
