pipe target output to hcat show nothing
Hello! In order to show some information in work_dir, hprintf in source code can always output string, however, if I use ./target 2>&1 | vmcall hcat in shell script e.g. agent.sh, usually I can't get anything, but sometimes it show someting
Did you find any specific bugs?
This is usually an issue with buffering in the pipe or ./target writing to other destinations like kernel log and not directly to console.
The most reliable option is to use hprintf() directly in your agent.
Sorry, I can't figure out it, it may be my own problem in using it, I will use hprintf() directly. If I figure out it someday, I will note it here. Thanks for your help!
