Dbsetseqno()

PURPOSE

set the sequence number in a table

SYNOPSIS

#include "dbl.h"
 
	int	dbsetseqno(dbf, seqno)
 
	<input parameter>
	char	*dbf;		/* .DBF file descriptor	*/
	long	seqno;		/* Sequence number to set	*/
 
	<output parameter>
	none

RETURN VALUE

The dbsetseqno() function returns 0 for success, or < 0 if an error occurs. See the section on return code values for a detailed list of return codes.

DESCRIPTION

The dbsetseqno() function sets the sequence number for a specified table (.DBF).

EXAMPLE

The following example sets the sequence number, then gets the sequence number.

#include <stdio.h>
#include "dbl.h"		/* Recital/Library include file		*/
#include "dblproto.h"		/* Recital/Library prototype file	*/
 
	static void errorproc(
		char	*func,
		char	*str,
		int	rc);
 
	main()
	{
	int		rc; 		/* Return Code for error handling		*/
	char		*dbf; 		/* File descriptor for table			*/
	long		*seqno; 	/* Buffer address for sequence number	*/
 
	rc = dbdcache(100);
	errorproc("dbdcache()","table cache specified.", rc);
	rc = dbfilemode(1,0);
	rc = dbopen("shipwreck.dbf", &dbf);
	errorproc("dbopen()","table opened shared.", rc);
 
	rc=dbsetseqno(dbf, (long) 49);
	errorproc("dbsetseqno()", "seqno set to 49.", rc);
	rc=dbgetseqno(dbf, seqno);
	errorproc("dbgetseqno()", "seqno retrieved.", rc);
	printf("t	  Seqno: t%dn", *seqno);
 
	rc = dbclose(dbf);
	errorproc("dbclose()", "table closed.", rc);
 
	exit(0);
}
 
	static void errorproc(func, str, rc)
	char	*func;
	char	*str;
	int	rc;
{
	if ( rc != SUCCESS ) {
	printf("n  Error performing function %s -> %dn", func, rc);
	exit(1);
	}
	printf("Function: t%s, t%s - Okn", func, str);
	return;
}
