Strange behaviour strstr() function

luc vercruysse

Hi,

I use RealView MDK-ARM 3.15b. When I call tge strstr function to search a substring in a larger string it always return NULL.
This is my code

  char* ptr;
  char str1[80] ;
  char str2[80];
  strcpy(str1,"This is a large string");
  strcpy(str2,"is");
  ptr  = strstr(str1,str2);

ptr is NULL.

Any idea ??

Kind regards
Luc
