DESCRIPTION

The MEMO_WRITE() function will update the specified memo field with the contents of the memo buffer. The space occupied by the memo in the memo in the memo file is not overwritten with the specified memo buffer. A value of -1 will be returned if the field is not a MEMO.

EXAMPLE

The following example updates the current contents of the specified memo with the value specified in the second parameter passed. It locks the record and then updates the record.

#include "dbapi.h"
 
dbapi_memo_write()
{
	int	result;
 
	if (_parinfo(1) == API_CTYPE && _parinfo(2) == API_CTYPE) {
 
	if (!DBF_ISEXCLUSIVE()) DBF_LOCKR(DBF_RECNO());
	result = MEMO_WRITE(_parc(1),_parc(2));
	if (result) result = DBF_UPDATE();
	if (!DBF_ISEXCLUSIVE()) DBF_UNLOCKR(DBF_RECNO());
 
	} else {
		result = -1;
	}
	_retni(result);
}
