If you need to support systems old enough that pipe only supports unidirectional pipes, then you're pretty much stuck with using pipe, fork, dup2, etc., on your own.Without showing code, it's hard to know.You seem to have answered your own question.The real question would be about the exact capabilities of the older systems in question.Mathieu Prevot schrieb: Hi, i import subprocess and use Popen, but pipe is not defined.Typedef boost_stream; file *myfile; / make sure to popen and it succeeds boost_stream stream(fileno(myfile t_auto_close(false / ost.C_str "r if (stream) while (!feof(stream) if (fgets(buffer, MAX_buffer, stream)!If your code needs to work on an older system that doesn't support popen opening bidirectional pipes, then you won't be able to use popen (at least not the one that's supplied).C_str "r null) return false; std:string cur_string while (fgets(buf, sizeof (buf fp) cur_string buf; out.
A guess is: if you use import subprocess then use subprocess.
I'd probably still wrap this up in a function that works almost like a modern version of popen, but instead of returning one file handle, fills in a small structure with two file handles, one for the child's stdin, the other for the child's stdout.
If they have a pipe that can wat hebben mens en milieu met elkaar te maken create a bidirectional pipe, but popen that doesn't, then I'd write the main stream of the code to use popen with a bidirectional pipe, and supply an implementation of popen that can use a bidirectional pipe that gets.Mathieu Jun 27 '08 # 4 This discussion thread is closed M 2019 Formerly "m" from About Bytes Advertise on Bytes Contact Us Sitemap Python Answers Sitemap Python Insights Sitemap Follow us to get the Latest Bytes Updates).Jun 27 '08 # 3, p: n/a, mathieu Prevot 2008/5/24 Diez.Pipe, or if using from subprocess import Popen make sure to do from subprocess import Popen, pipe Diez Indeed.Hi, i import subprocess and use Popen, but pipe is not defined.
