how to export gds file using skill

Something like this should do it:

    defun(CCSrunStrmout (lib cell view)
	let((streamOutKeys templateFile prt id)
	    streamOutKeys=ncons(nil)
	    streamOutKeys->libName=lib
	    streamOutKeys->primaryCell=cell
	    streamOutKeys->viewName=view
	    streamOutKeys->outFile="PIPO.log"
	    streamOutKeys->errFile="PIPO.err"
	    templateFile=makeTempFileName("./streamOutKeys")
	    prt=outfile(templateFile)
	    fprintf(prt "streamOutKeys='")
	    pprint(streamOutKeys prt)
	    newline(prt)
	    close(prt)
	    id=ipcBeginProcess(
		sprintf(nil "pipo strmout %s" templateFile)
		""
		CCSstrmDataHandler
		CCSstrmDataHandler
		CCSstrmExitHandler
	    ) ; ipcBeginProcess
            ; use ipcWait(id) if you want to wait for it to finish
	) ; let
    ) ; defun

    defun(CCSstrmDataHandler (_id data)
        printf("%s" data)
    )

    defun(CCSstrmExitHandler (_id status)
        printf("Stream Out exited with status %L\n" status)
    )

Note that I've not tested the above, it was modified from some similar code I already had, in order to protect the innocent...
