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.
