/*
**	IIerror -- std. equel error reporting routine.
**
**		IIerror is called either directly by a
**		routine detecting an error or by
**		IIrdpipe where INGRES returns an error.
**
**		In the case of an appropriate error, IIerrflag is set to
**		prevent the reading of the ovqp data pipe. This happens
**		on errors that happen during retrieves to C vars.
**
**		Errno is the error number: 1??? is an equel error
**		others are Ingres errors.
**
**		Argc and argv are structured as in Unix main program calls.
**
**		The error is printed if the call (*IIprint_err)()
**		returns > 0. Otherwise no error message is printed.
**		The error message that is printed is the one corresponding
**		to the number returned by (*IIprint_err)().
