Custom find and Replace functions in LoadRunner

There is no direct function in the GLOBAS.H definition//loadrunner that supports finding and replacing strings, so you can encapsulate a lr_replace function://-------------------------------------------  ---------------------------------Char *strreplace (const char *SRC, const char *from, const char *to) {char *value;  Char *dst;  Char *match;  int size;  int Fromlen;  int Tolen;  size = strlen (src) + 1;  Fromlen = strlen (from);    Tolen = strlen (To);  Value = (char *) malloc (size);  DST = value;    if (value = NULL) {for (;;)      {match = (char *) strstr (SRC, from);        if (match! = NULL) {size_t count = match-src;        Char *temp;        Size + = Tolen-fromlen;        temp = (char *) realloc (value, size);          if (temp = = NULL) {free (value);        return NULL;        } DST = temp + (dst-value);        Value = temp;        Memmove (DST, SRC, count);        src + = count;        DST + = count;        Memmove (DST, to, Tolen);        src + = Fromlen;      DST + = Tolen; } else {strcpy (DST, SRC);      Break }}} return value;} // ----------------------------------------------------------------------------// -------------------------------  ---------------------------------------------int lr_replace (const char *lrparam, Char *findstr, char *replacestr) {int  res = 0;  Char *result_str;  Char lrp[1024];  sprintf (LRP, "{%s}", Lrparam);  Result_str = Strreplace (lr_eval_string (LRP), findstr, REPLACESTR);    if (result_str! = NULL) {lr_save_string (result_str, Lrparam);    Free (RESULT_STR);  res = 1; } return res;
