#include <cruntime.h> int16_t __int16_mul(int16_t *muliplicand, int16_t multiplier);
__int16_mul_asgn updates the 16-bit signed integer pointed to by multiplicand by multiplying it by multiplier. The product is returned as the result. As only the lower 16 bits of the product are returned, __int16_mul returns correct products, modulo 16 bits, for both signed and unsigned arguments.
__int16_mul_asgn may not be provided on all implementations of CrossWorks.
