using unsigned short instead of short for input frame

Hi Speex Experts,Thanks for this great mailing list.

     i want to compress a frame of(uint16_t) audio samples, i found that speex codec assumes input frame of type short. fortunately,both data types are of  2-bytes , so my questions :
- can i cast data types for input to speex?, if so,can i cast uint16_t to unsigned short and still be accepted by speex ? ,
because i found converting from uint16_t to short does completely change the values of the samples(unsigned to signed !).

Any help or suggestion is appreciated. Thanks in advance.

Regards,
Mash'al
