Can some one pls help me the below function is returning with junk character

char   WSOH_SO_ID[11]; --> value is 3723611
char* FPART_SO_ID = "";
FPART_SO_ID = substr(WSOH_SO_ID, 0, 5);

char* substr(const char *src, int m, int n)
{
    // get length of the destination string
    int len = n - m;

    // allocate (len + 1) chars for destination (+1 for extra null character)
    char *dest = (char*)malloc(sizeof(char) * (len + 1));

    // start with m'th char and copy 'len' chars into destination 
    strncpy(dest, (src + m), len);

    // return the destination string
    return dest;
}

strncpy(dest, (src + m), len);

You will have to explicitly terminate the dest.

Read::

The strncpy() function is similar, except that at most n bytes of src are copied. Warning: If there is no null byte among the first n bytes of src, the string placed in dest will not be null-terminated.
