WebAs of C99 there are standard fixed width types. If you include stdint.h then you get int8_t, uint8_t, int16_t, uint16_t, etc. These have at least a fighting chance of being portable, since they're standard C, even if it is the newer, less-implemented standard. I'd recommend using stdint.h if you can, since it's less system-specific than types ... WebA tag already exists with the provided branch name.
