C read binary stdin

Question

I\'m trying to build an instruction pipeline simulator and I\'m having a lot of trouble getting started. What I need to do is read binary from stdin, and then store it in me

Answer 1

For Windows, this Microsoft _setmode example specifically shows how to change stdin to binary mode:

// crt_setmode.c
// This program uses _setmode to change
// stdin from text mode to binary mode.

#include <stdio.h>
#include <fcntl.h>
#include <io.h>

int main( void )
{
   int result;

   // Set "stdin" to have binary mode:
   result = _setmode( _fileno( stdin ), _O_BINARY );
   if( result == -1 )
      perror( "Cannot set mode" );
   else
      printf( "'stdin' successfully changed to binary mode\n" );
}

Answer 2

Consider using SET_BINARY_MODE macro and setmode:

#ifdef _WIN32
# include <io.h>
# include <fcntl.h>
# define SET_BINARY_MODE(handle) setmode(handle, O_BINARY)
#else
# define SET_BINARY_MODE(handle) ((void)0)
#endif
