I want to get the output of this command for example :
system("dir C:\");
or of :
QProcess::execute("cmd /c dir C:\");
How to do that ?
Thanks !
QProcess process;
process.start("cmd /c dir C:\\");
process.waitForFinished(-1);
QByteArray out = process.readAllStandardOutput();
You can modify the standard output path to be a pipe which you read from, but it would be easier to use popen()
instead of system()
.
Since you appear to be using Windows, you would use _popen()
.
#include <stdio.h>
....
FILE *fp = _popen("dir c:\", "r");
....
while (!feof(fp)) {
....
}
fclose(fp);
