In your test you use the $PMC variable instead of $PCM.

Don't put an ending ; on your script lines.

To read the file, use the following loop:
Code:
while read line
do
   . . . . 
done < $FILE

The field 2 can be read directly :
Code:
trunkPCM=100000
while read field1 PCM
do
   if [ -n "$PCM]
   then
      echo "$PCM, $trunkPCM"
      if [ $PCM -eq $trunkPCM ]
      then 
         trunkPCM=$PCM
      fi
   fi
done < $FILE

Jean-Pierre.

muroar_stream

muroar_stream(3)					    muRoar Programmer's Manual						  muroar_stream(3)

NAME

       muroar_stream - Create a stream connected to a RoarAudio sound server

SYNOPSIS

       #include <muroar.h>

       muroar_t muroar_stream (muroar_t fh, int dir, int * stream, int codec, int rate, int channels, int bits);

DESCRIPTION

       This  function connects a stream to a sound server supporting the RoarAudio protocol.  It takes a connected control connection created with
       roar_connect(3) and converts it into a connected stream. The socket can no longer be used as control connection.

PARAMETERS

       fh     The connected control connection.

       dir    The stream direction for the new stream.	For playback of a waveform stream (PCM data) this is MUROAR_PLAY_WAVE.	For  all  possible
	      values see the offical muRoar manual.

       stream This  is a pointer to an integer muRoar stores the stream ID in.	If your application does not need to know the stream ID of the new
	      stream this can be set to NULL.

       codec  This is the codec to be used for the new stream.	For signed PCM in host byte order use MUROAR_CODEC_PCM or MUROAR_CODEC_PCM_S.  For
	      unsigned	PCM  use MUROAR_CODEC_PCM_U.  There are a lot other codecs defined. However using a codec not supported by the server will
	      result an failure of this call.  For all possible values see the offical muRoar manual.

       rate   This is the sample/frame rate the new stream will use.  For streams this setting does not make any sense set this to zero.

       channels
	      This is the number of channels for the new stream.  For streams this setting does not make any sense set this to zero.

       bits   This is the number of bits per sample to be used by the data.  For streams this setting does not make any sense set this to zero.

RETURN VALUE

       On success this call return the new stream IO handle.  This may be the same as the control connection or a new one and the control  connec-
       tion is closed. On error, MUROAR_HANDLE_INVALID is returned.

BUGS

       In failure where is no way to tell was was going wrong.

HISTORY

       This function first appeared in muRoar version 0.1beta0.
