What programming language is that? C? Please tag your question to include the programming language. – Donald Duck Feb 16 '17 at 12:53

Do you mean `001` (an octal constant of type `int`, exactly equivalent to the decimal constant `1`), or `"001"`, a string literal? – Keith Thompson Feb 16 '17 at 19:56

The second argument of the C function strstr must be of type const char *. You are instead passing an int. Use quotes.
arg = strstr(buff, "001");

1The *parameter* is of type `const char*`. The *argument* can be `const char*` or `char*`. In this case it's of type `char*` (because C string literals, unlike C++ string literals, are not `const`). (`"001"` is actually of type `char[4]`, but it's implicitly converted at compile time to `char*`.) – Keith Thompson Feb 16 '17 at 19:57
