  23. Name            stpcpy - copies one string to another
  24.  
  25. Usage           char *stpcpy(char *destin, const char *source)
  26.  
  27. Prototype in    string.h
  28.  
  29. Description     stpcpy copies the bytes of source into destin and stops after
  30.                 copying the terminating null character of source. stpcpy (a, b)
  31.                 is the same as strcpy (a, b) except that the return values
  32.                 differ.
  33.  
  34.                 strcpy(a, b) returns a, while stpcpy (a, b) returns a +
  35.                 strlen (b).
  36.  
  37. Return value    returns destin + strlen(source);
