SysUtilsStrMove (C++)

Description

This example shows two functions that have the same effect as StrNew and StrDispose.

char * AHeapaString(char *S) {

Allocate string on heap.
 if ((S != NULL) && (S[0] != '\0'))
 {
   int L = StrLen(S) + 1;
   char *p = (char *)malloc(L);
   return StrMove(p, S, L);
 }
 return NULL;

}

Code

void DisposeDaString(char *S)
{
// Dispose string on heap
  if (S != NULL)
    free(S);
}
void __fastcall TForm1::Button1Click(TObject *Sender)
{
  char *S = "Now you see it.";
  char *otherS = AHeapaString(S);
  Canvas->TextOut(5, 10, otherS);
  Canvas->Refresh();
  Sleep(5000);
  DisposeDaString(otherS);
}
