TITLE : fstream-File Pointer-DOS Handle Equivalency Table




The following provides, in tabular format, the equivalent
functions between FILE pointers, C++ file Streams and DOS file
handles.

fstreams consist of fstreams, ifstreams and ofstreams. FILE
pointers are obtained from fopen, freopen, fdopen and other
functions. DOS handles are obtained from open, _open, create and
others.

FILE * FSTREAM HANDLE Notes:
====================================================================
fopen fp.open or open
constructor

fseek fp.seekp lseek

ftell fp.tellp tell 1.0 has bugs in
the tellp family

feof fp.eof eof

fread fp.read read

fwrite fp.write write

fileno (fp.rdbuf())->fd()

use fileno use fstrno chsize see below for
def of fstrno

fcloseall

fdopen fp.attach

ferror

fflush fp.sync

fgetc fp.get use read

fgetpos use tellp use tell

fsetpos use seekp use lseek
