Format
New(filename,timeout)
Args
filename: name of file or empty for temporary filetimeout: seconds to wait; -1 for no timeout
You call this via new/savefile(filename,timeout). The timeout is used to determine how long to wait if the file is locked. Normally (timeout=0), if the file is locked, the proc crashes with a runtime error. If you specify a timeout, then it will keep trying to open the file and if this fails, it will simply return with savefile.name being empty (ie a false value).
If the first argument is an entry in the world’s rsc cache, the data will be copied into a temporary file and accessed from there. Changes to this, and any other temporary file, are not saved. When you close the file, it simply gets deleted.
