C reading (from stdin) stops at 0x1a character

Question

currently I\'m implementing the Burrows-Wheeler transform (and inverse transform) for raw data (like jpg etc.). When testing on normal data like textfiles no problems occur.

Answer 1

As you've noticed, you're reading from stdin in ASCII mode and it is hitting the SUB character (substitute, aka CTRL+Z, aka DOS End-of-File).

You have to change the mode to binary with setmode while on Windows:

#if defined(WIN32)
#include 
#include 
#endif /* defined(WIN32) */

/* ... */

#if defined(WIN32)
_setmode(_fileno(stdin), _O_BINARY);
#endif /* defined(WIN32) */

On platforms other than Windows you don't run into this distinction in modes.
