In this second post about memory allocation, we take a look at memory management units (MMUs), and virtual and physical addressing.

QNX From The Board Up #11 - malloc() and mmap()

Take an introductory look at mmap() to allocate memory, then use it to write your own version of malloc(). (And build a KISS version of cat for your custom image!)
