This function is used to read data into the specified streambuf until the
|
|
streambuf's get area contains the specified delimiter. The call will block
|
|
until one of the following conditions is true:
|
|
</p>
|
|
<div class="itemizedlist"><ul class="itemizedlist" type="disc">
|
|
<li class="listitem">
|
|
The get area of the streambuf contains the specified delimiter.
|
|
</li>
|
|
<li class="listitem">
|
|
An error occurred.
|
|
</li>
|
|
</ul></div>
|
|
<p>
|
|
This operation is implemented in terms of zero or more calls to the stream's
|
|
read_some function. If the streambuf's get area already contains the delimiter,
|
|
the function returns immediately.

After a successful read_until operation, the streambuf may contain additional
|
|
data beyond the delimiter. An application will typically leave that data
|
|
in the streambuf for a subsequent read_until operation to examine.
