ipcBeginprocess!

hi, 

  I write a skill function to collect some simulation information, it shows like the following code

procedure(zfGetBeginTime()
readBeginTimeIpc=ipcBeginProcess("date")
simulationBeginTime=ipcReadProcess(readBeginTimeIpc)
fp=outfile("~/skill/timeConsumption.out")
fprintf(fp "%s " simulationBeginTime)
close(fp)
)

but, i found that, i can get the right info if i type these command in CIW one by one. i will get only "t" in the file(pointer) if i run this procedure in CIW, i can't understand it, so please give me some advice if you know this.

Regards,

zfeng

     In general you should call ipcWaitForProcess() before calling ipcReadProcess - this waits until the process is up and running and ready to be communicated with. Alternatively use ipcWait as Quek suggested to wait until the process has ended - the choice would depend on whether you really want to wait for it to finish.

    Regards,

    Andrew.
