read from process ?stderr?

[Kevin]

Hi, I am looking for a built-in command or function to read from the stderr of another process. I am unable to locate anything in the dictionary or various web-sites. I realize I can redirect stderr to stdout however this would vastly complicate the application.

Thanks in advance for any assistance,

K

You can direct your stderr to a text file which can then be read into a LiveCode field or variable.

Thanks, however redirecting to a file is not acceptable for this implementation as all the standard pipes are streaming. I guess I will look into the FFI I have been reading about. I believe the official product is called LiveCode Builder. It would be interesting to use it for loading dynamic libs (DLLs in windows) ldsym, dlopen etc.? I have used binaryEncode and binaryDecode which is similar to pack and unpack methods I have used in other programming languages. So, the concepts are not foreign to me. If you have any further suggestions they would be appreciated.

Thanks!

Maybe this?:

Code: Select all

command-name 2>&1

Can you do that inwith LiveCode?

Are you using the shell function to call your CLI process?

Um . . .

redirecting to a file is not acceptable

Hmmm... Is that the full error message?

Do you also get that error message in terminal?

It could be the tutorial I linked to is wrong, but it would be good to see the script you used to produce that error.
