/** \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().
