Answer 1

The MSVC solution is:

#include 
#include 
...
_setmode(1,_O_BINARY)

Other runtimes may provide the C99 solution or an alternate way. EDIT: I believe setmode([file number],O_BINARY) originated on Borland Turbo C, and other compilers for MS-DOS and Windows imitated it. The _ prefix is done to keep the namespace clean, and may not be present on some compilers.
