hi,
could u plz tell me abt the initialisation of the
buffers i.e.
typedef struct {
Int16 *bufOrigin;
Int16 *bufPastEnd;
Int16 *bufCurrent;
} BufPtrs;
......i'm getting an error for Memmove func. saying
tht memmove to null, as i'm using the function without
initialising the first parameter i.e. the destination
buffer.
thanx,
VS
