  15. int strstr(char *data, char *chunk)                          
  16. {                                                            
  17.         static int x;

  26. What's wrong with this subroutine?  I'm making strstr() since Amiga C
  27. doesn't have it.
  28. I do stuff like ..  d  = strstr("foobar", "bar");
  29. and d comes up like 139579275 or some weird value, where it's SUPPOSED to
  30. return either 0 (not found) or some value x, where x is the position in the
  31. string where "bar" starts.  When I say
  32.  
  33. int strstr(char *data...
  34.  
  35. Can I pass both *str and str[25]?  For instance..
  36.  
  37.    char *blah;
  38.  
  39.    s = strstr(blah....  /* after malloc()'ing it, of course */
  40.  
  41.   or  char blah[50];  Could either blah be passed into strstr as a (char *)?
  42.  
  43. Again, reply via email, please.  shulick@indiana.edu
  44. Thanks.
