public async string read_upto_async (string stop_chars, ssize_t stop_chars_len, int io_priority = DEFAULT, Cancellable? cancellable = null, out size_t length) throws IOError
The asynchronous version of read_upto.
It is an error to have two outstanding calls to this function.
In contrast to read_until, this function does not consume the stop character. You have to use read_byte to get it before calling read_upto again.
Note that stop_chars may contain '\0' if stop_chars_len is specified.
When the operation is finished, callback will be called. You can then call read_upto_async.end
to get the result of the operation.
