I'm reading through /usr/src/sys/dd/dd.h, and I noticed the following lines:

39 u_char *db; /* buffer address */ 40 u_char *dbp; /* current buffer I/O address */

Why was u_char used instead of uint32_t? Aren't pointers always 32 bits on a 32 bit machine?

You're confusing the type of the pointer w/ a pointer... These are correct, please read a basic intro to pointers in C...
