getNthRestart

Function: getNthRestart { n -> id data rFn iFn tFn fn name }

file: job.t
package: muf
status: alpha

This function returns the contents of the nth restart from the top of the loop stack, along with a value which may be used to refer to it in future (the integer offset of the restart within the stack, as it happens -- but code should not be written to depend on this). The top restart is number zero.

The return values are:

name

:name symbol specified when creating restart.

fn

:function function specified when creating restart.

tFn

:testFunction function specified when creating restart.

iFn

:interactiveFunction function specified when creating restart.

rFn

:reportFunction function specified when creating restart.

data

:data value specified when creating restart, else nil.

id

nil if no nth restart was found, else a restart label usable with getRestart.
