int free (void)
Return the number of free elements in the buffer.
bool readable (void)
Check if there are any emelemnt available (readble / not empty)
int size (void)
Get the number of values available in the buffer return the number of element available.
T getc (void)
get a single value from buffered pipe (this function will block if no values available)
int get (T *p, int n, bool t=false)
int set (int ix)
