Hm, no, the declarations of cblas_sdot seems to be the same.


NumPy:

float  cblas_sdot(const int N, const float  *X, const int incX,
                   const float  *Y, const int incY);


Apple:

float  cblas_sdot(const int N, const float  *X, const int incX,
                   const float  *Y, const int incY) 
__OSX_AVAILABLE_STARTING(__MAC_10_2,__IPHONE_4_0);
