ipcBeginprocess!

imagesensor123

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

  • Hi zfeng

    I think solution 1832836 will be useful in explaining this. You can resolve the problem by adding a small timeout value to ipcReadProcess. E.g.

    ipcReadProcess(readBeginTimelpc 1)

    OR

    You can use ipcWait:

    readBeginTimeIpc=ipcBeginProcess("date")
    ipcWait(readBeginTimelpc)
    simulationBeginTime=ipcReadProcess(readBeginTimeIpc)
