read_upto_async

Description:

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, 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.

this	a DataInputStream
stop_chars	characters to terminate the read
stop_chars_len	length of `stop_chars`. May be -1 if `stop_chars` is nul-terminated
io_priority	the I/O priority of the request
cancellable	optional Cancellable object, null to ignore
callback	callback to call when the request is satisfied
user_data	the data to pass to callback function
