dlcommit - log committed transaction
Dlcommit records in the log file a marker indicating that the
transaction should complete and that the process has every
intention of doing so. Trid is the value returned by a previous
call to dlbegin.
At the present time, committed transactions have no special
meaning and are provided only
for documenting transactions in the log file.
dlbegin(C-3), dlcancel(C-3), dlend(C-3)
A value of -1 is returned if the transaction marker cannot be
recorded in the log file. In this case, the RMS error message is
set describing the problem.
