FILE:
DB2TextFile.h
DESCRIPTION:
Declaration of cDB2TextFile class
PUBLIC CLASSES AND METHODS:
cDB2TextFile
The cDB2TextFile class provides the simple ability to read in an
ANSI/UNICODE file and copy it to a dynamically allocated buffer
The sole difference between this and CStdioFile is that the issues
stemming from supporting both ANSI and UNICODE files are handled
in a simpler fashion at the expense of a bit of performance
