rules for implementing string funktions with repetive call
PostPosted: Tue Dec 21, 2004 7:27 am     Reply with quote
I have a problem with pointers to constant strings. I have read the forum and recognised that this is a big issue and mater. But what I tried to do is to compare a string with a constant string. It works in a symilar function strcpy.

Code:
strcpy(temp_string, "const string"); // That woks
copy(temp_string, "const string");   // Renamed function dosen't work


I simply tried to rename that function but it dosen't worke:


Code:
char *strcpy(char *s1, char *s2) //This funktion works
{
  char *s;

  for (s = s1; *s2 != 0; s++, s2++)
     *s = *s2;
  return(s1);
}


char *copy(char *s1, char *s2) //This function dosen't work
{
  char *s;

  for (s = s1; *s2 != 0; s++, s2++)
     *s = *s2;
  return(s1);
}

Does any one have an idea for that phenomenon?
What are the rules for implementing string funktions with repetive call in CCS?

Thanks

Probably both routines doesnt work, but CCS have an internal "strcpy" and probably it is using it.
