    \brief Parses the string into tokens.

    strtok_P() parses the string \p s into tokens. The first call to
    strtok_P() should have \p 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_P().
    The delimiter string \p delim may be different for each call.

    The strtok_P() function is similar to strtok() except that \p delim
    is pointer to a string in program space.

    \returns The strtok_P() function returns a pointer to the next token or
    NULL when no more tokens are found.

    \note strtok_P() is NOT reentrant. For a reentrant version of this
    function see strtok_rP().
