NAME

bkcheck - Memory integrity check routine

USAGE

call bkcheck(ptr, errcode)

DESCRIPTION

Performs an integrity check on a specificblock allocated with hpalloc. Each control byte is examined to ensure that it has not been overwritten. If any over-indexing is detected, bkcheck will give an error message and a potential traceback for the corrupted block. bkcheck can be called many times in the same program in order to determine more precisely where a particular block as been corrupted.
