/** \ingroup avr_string
    \fn char *strtok(char *s, const char *delim)
    \brief Parses the string s into tokens.

    strtok parses the string s into tokens. The first call to strtok
    should have s as its first argument. Subsequent calls should have
    the first argument set to NULL. If a token ends with a delimiter, this
    delimiting character is overwritten with a '\\0' and a pointer to the next
    character is saved for the next call to strtok. The delimiter string
    delim may be different for each call.
    
    \returns The strtok() function returns a pointer to the next token or
    NULL when no more tokens are found. 
    
    \note strtok() is NOT reentrant. For a reentrant version of this function
    see \c strtok_r().
