I can give a few pointers as I designed the bash script 'AudioScope.sh' here: AudioScope Project. to include it.
It captures using the now defunct 'SoundRecorder.exe' for Windows 8.1 OR CygWin's builtin '/dev/dsp'. Both methods take around 2 seconds total for a 1 second burst, BUT, because CygWin is _emulating_, (for want of a better description), a UNIX style environment accessing either capture mode takes around 1/8th of a second berfore the audio device activates.
SoundRecorder.exe, (which is no longer part of Windows 10), can only do a standard '.wav' file at 44100sps and /dev/dsp a '.raw' unsigned integer file at 8000sps from the command line.
The 'mintty' terminal is quite capable of all the escape codes I have used so far, including the title bar.
The above shell project was designed for hopefully ALL *NIX flavours with bash and included SoX, a dependency, as the prime mover for capture.

Stomp::commit - Commits a transaction in progress

       Object oriented style (method):

SYNOPSIS
public bool Stomp::commit (string $transaction_id, [array $headers]) DESCRIPTION
Procedural style: bool stomp_commit (resource $link, string $transaction_id, [array $headers]) Commits a transaction in progress. PARAMETERS
o $link -Procedural style only: The stomp link identifier returned by stomp_connect(3). o $transaction_id - The transaction id. o $headers -Associative array containing the additional headers (example: receipt). RETURN VALUES
Returns TRUE on success or FALSE on failure. NOTES
Tip Stomp is inherently asynchronous. Synchronous communication can be implemented adding a receipt header. This will cause methods to not return anything until the server has acknowledged receipt of the message or until read timeout was reached. EXAMPLES
Example #1 Object oriented style <?php /* connection */ try { $stomp = new Stomp('tcp://localhost:61613'); } catch(StompException $e) { die('Connection failed: ' . $e->getMessage()); } /* begin a transaction */ $stomp->begin('t1'); /* send a message to the queue */ $stomp->send('/queue/foo', 'bar', array('transaction' => 't1')); /* commit */ $stomp->commit('t1'); /* close connection */ unset($stomp); ?> Example #2 Procedural style <?php /* connection */ $link = stomp_connect('tcp://localhost:61613'); /* check connection */ if (!$link) { die('Connection failed: ' . stomp_connect_error()); } /* begin a transaction */ stomp_begin($link, 't1'); /* send a message to the queue 'foo' */ stomp_send($link, '/queue/foo', 'bar', array('transaction' => 't1')); /* commit */ stomp_commit($link, 't1'); /* close connection */ stomp_close($link); ?> PHP Documentation Group STOMP_COMMIT(3)
