25 * and is therefore thread and reentrancy-safe.
27 * Any leading delimiters in str are skipped. Then the string is scanned
28 * until an additional delimiter or end-of-string is found. The final
29 * delimiter is set to '\0'.
31 * @param aDelims The set of delimiters.
32 * @param aStr The string to search. This is an in-out parameter; it is
33 * reset to the end of the found token + 1, or to the
34 * end-of-string if there are no more tokens.
35 * @return The token. If no token is found (the string is only
36 * delimiter characters), nullptr is returned.
