 * @brief Standardized argument parsing function.

 * The `argsplit()` function parses a input string and splits it into a NULL-terminated array of strings factoring in
 * escape chars spaces and quotation marks.
 *
 * @param str The input string to be parsed.
 * @param maxLen The maximum length of the input string.
 * @param count A pointer to a `uint64_t` where the number of parsed arguments will be stored.
 * @return On success, returns a `NULL`-terminated array of strings (the parsed arguments). On failure, returns `NULL`.

/**
 * @brief Standardized argument parsing function using a provided buffer.
 *
 * The `argsplit_buf()` function is similar to `argsplit()` but uses a pre-allocated buffer for storing the parsed
 * arguments, useful for memory management.
 *
 * @param buf A pointer to the buffer to be used for storing the parsed arguments.
 * @param size The size of the provided buffer.
 * @param str The input string to be parsed.
 * @param maxLen The maximum length of the input string.
 * @param count A pointer to a `uint64_t` where the number of parsed arguments will be stored.
 * @return On success, returns a `NULL`-terminated array of strings (the parsed arguments) stored within the provided
 * buffer. On failure, returns `NULL`.
