void MLReleaseUTF8String(MLINK link, const unsigned char *s, int len)
disowns memory allocated by MLGetUTF8String()to store the UTF-8 encoded string s.
  • MLReleaseUTF8String() is declared in the MathLink header file mathlink.h.
#include "mathlink.h"

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

    const unsigned char *string;
    int number_of_bytes;
    int number_of_characters

    if(! MLGetUTF8String(lp, &string, &number_of_bytes, &number_of_characters))
        { /* unable to read the UTF-8 encoded string from lp */ }

    /* ... */
