octave: Allocating Local Memory in Oct-Files

 
 A.1.10 Allocating Local Memory in Oct-Files
 -------------------------------------------
 
 Allocating memory within an oct-file might seem easy, as the C++
 new/delete operators can be used.  However, in that case great care must
 be taken to avoid memory leaks.  The preferred manner in which to
 allocate memory for use locally is to use the ‘OCTAVE_LOCAL_BUFFER’
 macro.  An example of its use is
 
      OCTAVE_LOCAL_BUFFER (double, tmp, len)
 
 that returns a pointer ‘tmp’ of type ‘double *’ of length ‘len’.
 
    In this case, Octave itself will worry about reference counting and
 variable scope and will properly free memory without programmer
 intervention.
