.SH NAME
tcftest \- test cases of the fixed-length database API

.SH DESCRIPTION
.PP
The command `\fBtcftest\fR' is a utility for facility test and performance test.  This command is used in the following format.  `\fIpath\fR' specifies the path of a database file.  `\fIrnum\fR' specifies the number of iterations.  `\fIwidth\fR' specifies the width of the value of each record.  `\fIlimsiz\fR' specifies the limit size of the database file.
