There is.  However, try the following:

    ptr = (variable type *)NewPtr(size needed);
    
the C allocators used in Lightspeed end up calling NewPtr anyway.  To
deallocate try:

    DisposPtr(ptr);

Look in the addendum to Lightspeed C 2.14 for a more detailed example or
if you have THINK C 3.0, they have examples right in the manual.

No Prob.
