    Real length of a char string?

    The length of a character string is usually identified by the first null byte. But what if you had read a binary file? Files are filled with null bytes. I know fread returns the amount of bytes read, but is there another way?

    So strlen("123456") returns 6;

    strlen("123456\07"), that is 1,2,3,4,5,6,NULLBYTE,7, and that returns 6. Any otehr way?
