(...) According to config/h8300/h8300.h in the gcc sources, int is 32bit for the h8 cross compiler. I believe the reason mm_free_mem() returns an int is because the memory manager stores the size of each free block as size_t, which is defined in (...)

(...) int is defined as the natural width of the processor, which on a 16-bit processor is 16 bits. longs are 64 bits on some machines as well, so you can't assume it is always 32 bits -- if your code cares, use sizeof. (...) 32-bit math on the H8 (...) (22 years ago, 12-Jul-02, to lugnet.robotics.rcx.legos)

That is very interesting Jason. It is interesting that mm_free_mem() returns a 16bit value using a 32bit return code. Both int and long are 32bit value on most computers/compilers these days; short would be a 16bit value; and char would be an 8bit (...) (22 years ago, 11-Jul-02, to lugnet.robotics.rcx.legos)

While the declaration for mm_free_mem is int mm_free_mem(void) The fact is that the RCX has only 32K of memory available. 32K in hex is 0x8000... there's never a need for more than 4 digits in hex. Looking at key_handler() in kernel/program.c (the (...) (22 years ago, 11-Jul-02, to lugnet.robotics.rcx.legos)
