virtual bool isBOF() const;
Return Value
True if the dataset contains no records or if you have scrolled backward before the first record, otherwise false.
Description
Call this member function before you scroll from record to record to learn if the current record pointer is positioned to the first record of the dataset. You can also use isBOF with isEOF to determine whether the dataset contains any records or is empty.
Example
dataset.open();
if (dataset.isBOF())
return; // dataset is empty
// scroll to last record
dataset.last();
// scroll to first record
while (!dataset.isBOF()
dataset.prev();
