MathLink C Function


void MLReleaseUTF32Symbol(MLINK link, const unsigned int *s, int len)
disowns memory allocated by MLGetUTF32Symbol() to store the UTF-32 encoded character string s corresponding to the name of a symbol.
  • MLReleaseUTF32Symbol() is declared in the MathLink header file mathlink.h.
#include "mathlink.h"

/* read a UTF-32 encoded symbol from a link and then release the memory to MathLink for deallocation */

void f(MLINK lp)
    const unsigned int *symbol;
    int length;

    if(! MLGetUTF32Symbol(lp, &symbol, &length))
        { /* unable to get UTF-32 encoded symbol from lp */ }

    /* ... */

    MLReleaseUTF32Symbol(lp, symbol, length);
