MathLink C Function


void MLReleaseUTF8Symbol(MLINK link, const unsigned char *s, int len)
disowns memory allocated by MLGetUTF8Symbol() to store the UTF-8 encoded character string s corresponding to the name of a symbol.
  • MLReleaseUTF8Symbol() is declared in the MathLink header file mathlink.h.
#include "mathlink.h"

/* read a UTF-8 encoded symbol from a link and then release the memory to MathLink for deallocation */

void f(MLINK lp)
    const unsigned char *symbol;
    int number_of_bytes;
    int number_of_characters;

    if(! MLGetUTF8Symbol(lp, &symbol, &number_of_bytes, &number_of_characters))
        { /* unable to read the UTF-8 encoded symbol from lp */ }

    /* ... */

    MLReleaseUTF8Symbol(lp, symbol, number_of_bytes);
