FAL Functions

The FAL includes the following C functions (Visual C++ for Windows 2000/2003/Windows NT systems):

•Opening a dataset: datasetOpen (see section Opening a Dataset)

•Reading one record from a dataset: datasetGet (see section Reading Data)

•Writing one record to a dataset: datasetPut (see section Writing Data)

•Closing a dataset: datasetClose (see section Closing a Dataset)

•Acquiring error information: datasetGetLastError (see section Acquiring Error Information)

•Acquiring dataset attribute information (see section Acquiring Dataset Attributes):

datasetGetFileInformation datasetFindNextFile datasetFindFirstFile datasetFindClose
