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.

Parameters:

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
