C read binary stdin
C read binary stdin 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 memory somehow while I manipulate the data. I need to read in chunks of exactly 32 bits one after the other. How do I read in chunks of exactly 32 bits at a time? Secondly, how do I store it for manipulation later? Here's what I've got so far, but examining the binary chunks I read further, it just doesn't look right, I don't think I'm reading exactly 32 bits like I need. char buffer[4] = { 0 }; // initialize to 0 unsigned long c = 0; int bytesize = 4; // read in 32 bits while (fgets(buffer, bytesize, stdin)) { memcpy(&c, buffer, bytesize); // copy the data to a more usable structure for bit manipulation later // more stuff buffer[0] = 0; buffer[1] = 0; buffer[2] = 0; buffer[3] = 0; // set to zero before next loop } fclose(stdin); How do I read in 32 bits at a ti...
