GCC Fixed Size Integers

Question

On the MSVC++ compiler, one can use the __int8, __int16, __int32 and similar types for integers with specific sizes. This is extremely useful for applications which need to work with low-level data structures like custom file formats, hardware control data structures and the like.

Is there a similar equivalent I can use on the GCC compiler?

Answer 1

In POSIX, stdint.h defines these. You can use:

uint8_t  - unsigned 8 bit
int8_t   - signed 8 bit
uint16_t - unsigned 16 bit
int16_t  - signed 16 bit
uint32_t - unsigned 32 bit

etc... I used these types all the time.
