What is the most common way to represent a byte array in C?

Question

Would we use char , signed char , unsigned char or import some header for a byte type?

My code is going to be seen/used by other C developers and I want to use whatever standard they're most likely used to seeing.

Also, I may be allocating memory for this function from python as a numpy array and calling it through ctypes. Is there a preferred way to allocate a byte array in numpy?

Is np.zeros(size, dtype=np.byte) the normal way, if the corresponding C type is char , for example?

Answer 1

The most common way is using a char array. However, it really depends on the needs of the code.
