Question

GCC 4.4.1, C99

I am using size_t, and size_t is an unsigned int. However, that depends if you are running 32 bit or 64 bit.

I will be using size_t to store the size of a buffer.

So I don’t think this would be very portable if using across architectures.

Just a question, with using size_t on either a 32 or 64 bit. What situations would cause the most serious problem?

Answer 1

size_t is guaranteed to be able to hold the number of bytes of any object on your implementation.
That’s why the return type of sizeof is size_t.

So yes, it’s portable.
