## FLgetsnap

FLgetsnap — Retrieves a previously stored FLTK snapshot.

## Description

Retrieves a previously stored snapshot (in memory), i.e. sets all valuator to the corresponding values stored in that snaphot.

## Syntax

    inumsnap FLgetsnap index

## Initialization

inumsnap -- current number of snapshots.

index -- a number referring unequivocally to a snapshot. Several snapshots can be stored in the same bank.

## Performance

FLgetsnap retrieves a previously stored snapshot (in memory), i.e. sets all valuator to the corresponding values stored in that snapshot. The index argument unequivocally must refer to an already existing snapshot. If the index argument refers to an empty snapshot or to a snapshot that doesn't exist, no action is done. FLsetsnap outputs the current number of snapshots (inumsnap argument).
