NAME

AConnectRecordSStream − connect socket to TCP socket address; return transaction ID

SYNOPSIS

#include <audio/Alib.h>

ATransID AConnectRecordSStream (

Audio *audio,

SStream *remote_sstream,

SSRecordParams *rp,

long *status_return

);

DESCRIPTION

AConnectRecordSStream() is used by an application that is preparing to send a record sound stream to a server on another system.  After creating a socket, the application calls AConnectRecordSStream() to connect it to the other server at the TCP socket address contained in remote_stream, the pointer to which it obtains from the application that controls the other server. The call returns a transaction ID for the operation. 

audio specifies the Audio structure associated with this application’s connection to its own server. 

remote_sstream is a structure containing a TCP socket address, audio attributes, and the maximum block size, in bytes, of each transfer of audio data over the connection. 

rp is the structure containing the record gain, pause_first toggle, gain matrix, and the mask for event notification. 

status_return receives the returned status of the operation unless it is set to NULL. 

RETURN VALUE

Upon successful completion, AConnectRecordSStream() returns a transaction ID. 

ERRORS

If status_return is not set to NULL, one of the following is returned in status_return:

 0 AENoError

 2 AEBadAudio

10 AEBadGainMatrix

21 AEBadSoundStream

EXAMPLES

The following example connects a socket to another server’s TCP socket address and returns a transaction ID for the operation. 

ATransID xid;            /* transaction ID */
Audio *audio;            /* audio connection */
SStream *r_sstream;      /* remote stream descrip */
SSRecordParams *ss_rp;   /* sstream record params */
long status;             /* error status */
.
.
.
/* connect to TCP socket addr and get transID */
xid = AConnectRecordSStream(audio, r_sstream, ss_rp, &status);

DEPENDENCIES

This function belongs to the Audio Library of functions that manage connections to an audio server.  The audio server must run on a system that has audio hardware.  To find out whether or not your system has audio hardware, refer to the hardware manual that accompanies your system.
