DMMS (Dynamic Memory Management System)

NAME

memoirc - Memory integrity check function

USAGE

ier = memoirc(msg_lvl)

DESCRIPTION

Performs an integrity check on all blocks allocated with the DMMS package. Each control byte is examined to ensure that it has not been overwritten. If any over-indexing is detected, memoirc will give an error message and a potential traceback for the corrupted block. memoirc can be called many times in the same program in order to determine more precisely where a particular block has been corrupted. Upon completion, memoirc returns 0 if no error was detected; otherwise, a negative integer code will indicate the error type.

msg_lvl

Integer variable, may take values 0 or 1. If set to 1, an informative message(block check ok) will be issued for each block being checked. If set to 0, no messages other than error messages will be issued.
