NAME

isbegin - begins a transaction

SYNOPSIS

error = isbegin (void)

DESCRIPTION

The isbegin function starts a transaction. All operations executed upon a transactional file descriptor become part of the transaction. Operations on nontransactional file descriptors are unaffected. Once isbegin is called, it may not be called again until either isrollback or iscommit has been called. 

CAUTIONS

If isbegin is called more than once before either iscommit or isrollback is called, the results may be unpredictable.
