Stores an integer as 16 bits in the file. Note: The value should lie in the interval $(D 0, 2^16 - 1). Any other value will overflow and wrap around. To store a signed integer, use store64 or store a signed integer from the interval $(D -2^15, 2^15 - 1) (i.e. keeping one bit for the signedness) and compute its sign manually when reading. For example:
