int16 arrays in inline c code

[baldursigurds]

A simple question about C code, which will run on a Bangle.js. How do I define an array of sixteen bit signed integers?

I have data coming in from a sensor in this format, and a function headed by void float_win(int a, int b, int* asdf, float* d), compiled by E.compiledC. Here, asdf is a pointer to the array coming from E.getAddressOf(x,true), where x is an arraybuffer where two bytes together represent one signed 16 bit integer.

This doesn't work, since int assumes a 32 bit integer, this can be verified as follows: two int16 zeroes together (32 zero bits) give one zero, and two int16 -1 together (32 bits of 1) give one -1.

I tried using the type int16_t*, but the compiler complains about it. Is there a name for this type in the C used by the compiler? Otherwise, I would have to resort to some bit shuffling tricks to seperate adjacent data.

Ok, I think the answer to this question is short. Never mind :)

Yes - that's the one! short to interpret it as -32768..32767 and unsigned short if you want to interpret those 16 bits as 0..65535
