Here we implement them * as static inline functions wrapping around memcpy and memset. */ #include <string.h> static inline void Copy ( const Word16 x[], /* (i) : input vector */ Word16 y[], /* (o) : output vector */ Word16 L /* (i) : vector length */ ) { memcpy(y, x, L * 2); } static inline void Set_zero ( Word16 x[], /* (o) : vector to clear */ Word16 L /* (i) : length of vector */ ) { memset(x, 0, L * 2); }
