Low level I/O functions for audio input from adinnet client. The adinnet server/client is a scheme to transfer speech data via tcp/ip network with segmentation information, implemented for Julius. When this input is selected, Julius becomes adinnet server and wait for a client to connect. The sample client "adintool" is also included in Julius package.
This input works on Linux, Windows and most OS where Julius can run.
"EsounD" is an another method of obtaining audio input from network on Linux. See adin_esd.c for details.

| boolean adin_tcpip_standby | ( | int | freq, | |

End recording.
If last input segment was segmented by end of connection, close socket and wait for next connection. Otherwise, it means that the last input segment was segmented by either end-of-segment signal from client side or speech detection function in server side, so just wait for a next input in the current socket.

| int adin_tcpip_read | ( | SP16 * | buf, | |
| int | sampnum | |||
| ) |
Try to read sampnum samples and returns actual sample num recorded.
This function will not block.
If data of zero length has been received, it is treated as a end-of-segment marker from the client. If data below zero length has been received, it means the client has finished the overall input stream transmission and want to disconnect.
| buf | [out] samples obtained in this function | |
| sampnum | [in] wanted number of samples to be read |
