tcfmttest \- test cases of the fixed-length database API

.SH DESCRIPTION
.PP
The command `\fBtcfmttest\fR' is a utility for facility test under multi\-thread situation.  This command is used in the following format.  `\fIpath\fR' specifies the path of a database file.  `\fItnum\fR' specifies the number of running threads.  `\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.
