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

    See that "Support" menu choice at top of the page?

    That is the route to Keil support. This forum is not. "Terms of Use" (link you can see at left of this post) contains the following text:

    Thanks for response.

    I contacted Keil support, but the support for my product has expired...
    However I found out that the problem only occur when I use the microlib.
    Knowing this I googled and did find a patch (RVS31-PA-00002-r3p1-11rel0) that installs a new version of the lib where the problem is solved. Thanks again.

    Kind regards
