Top Forums Shell Programming and Scripting Creating a pseudo-array in dash, (POSIX). Post 303028617 by wisecracker on Friday 11th of January 2019 08:46:31 AM

@ Don...

Each element in the pseudo-array will be a ASCII number from 0 to 255 decimal the value of an 8 bit byte, (so therefore 1 to 3 characters long); a simple audio sample.
(However it could be a 2 byte word from 0 to 65535 decimal, depends how I feel; a more accurate sample if I decide.)
I used newlines as an element separator in one of my examples but any IFS value would probably be OK by me...

You mention ed and I have never, ever used it and I like the idea you put forwards so man page and www it is to see the possibiities.
Is there a limit to POSIX's number of variables, or is that limited to available real memory and element sizes?

@ Jim M...

I code for pure fun and I really love trying the _impossible_ and making languages do stuff they were not designed to do.

@ Scrutinzer...

Not in my local environment at the moment but will try your method out.

AuMakeElementExportClient(3)				     Library Functions Manual				      AuMakeElementExportClient(3)

Name
       AuMakeElementExportClient - initialize an ExportClient element

Synopsis
       #include <audio/audiolib.h>

       AuMakeElementExportClient(element, input, sample_rate, format, num_tracks, discard, max_samples, high_water_mark, num_actions, actions)
	   AuElement *element; /* RETURN */
	   unsigned short input;
	   unsigned short sample_rate;
	   unsigned char format;
	   unsigned char num_tracks;
	   unsigned char discard;
	   AuUint32 max_samples;
	   AuUint32 high_water_mark;
	   int num_actions;
	   AuElementAction *actions;

Arguments
       element	 Returns the initialized element.

       input	 Specifies the index of the element to supply the audio data to this element.

       sample_rate
		 Specifies the sample rate of the audio data.

       format	 Specifies  the  format  of the audio data.  Currently, the following formats are defined: AuFormatULAW8, AuFormatLinearUnsigned8,
		 AuFormatLinearSigned8, AuFormatLinearSigned16MSB, AuFormatLinearUnsigned16MSB, AuFormatSignedLinear16LSB,  and  AuFormatLinearUn-
		 signed16LSB.

       num_tracks
		 Specifies the number of tracks in the audio data.

       discard	 Specifies if the flow should pause initially.	Normally AuTrue.

       max_samples
		 Specifies the maximum number of samples to send to the client in a single write.  Ignored for "trivial" flows.

       high_water_mark
		 Specifies  when to tell the client application to read the audio data from the server.  When this number of samples is reached in
		 the buffer, an ElementNotify event with kind set to AuElementNotifyKindHighWater will be sent to the client application.

       num_actions
		 Specifies the number of actions in actions.

       actions	 Specifies the list of actions to associate with this element.	Entries in this list can be initialized with  AuMakeChangeStateAc-
		 tion, AuMakeSendNotifyAction, and AuMakeNoopAction.  May be NULL.

Description
       AuMakeElementExportClient  sets	the type member of element to AuElementTypeExportClient and initializes the exportclient member of element
       with the remaining arguments.

       AuMakeElementExportClient is implemented as a macro.
