// Wrapper class for CFile. It allows us to use CPascalString for
|
|
// file names, and does some 'text mode' read/write operations.
|
|
// This class contains a pointer to a CFile but contains most of
|
|
// the CFile methods thus it can be used as a CFile. CLFile will either
|
|
// use an existing CFile provided at construction time or it will create its
|
|
// own CFile as needed. In either case, the enbeded CFile is destroyed when
|
|
// the CLFile is destroyed.
