The next functions that I meet are to centralize all the access to one
 or more binary files in CA-Clipper.

    The functions offered check all kind of error that could be produced
 in a CA-Clipper program when it access to binary files, like are, the file
 doesn't exist, try to access to a file without lock it before cause the
 blockades are made automaticly.

    Besides, you'll be able to forget the I/O errors due all file access
 functions retry the operation and inform the user if there's some error.
