MLReleaseReal32List()

void MLReleaseReal32List(MLINK link, float *a, int n)
disowns memory allocated by MLGetReal32List() to store the array a of length n.
  • MLReleaseReal32List() is declared in the MathLink header file mathlink.h.
#include "mathlink.h"

/* read a list of single-precision floating-point numbers from a link and then release the memory to MathLink for deallocation */

void f(MLINK lp)
{
    float *data;
    int length;

    if(! MLGetReal32List(lp, &data, &length))
     { /* unable to read the list of floating-point numbers from lp */ }

    /* ... */

    MLReleaseReal32List(lp, data, length);
