Have a question regarding file descriptors and vfork(). I assume the following possible, because the original dvdplayer.bin application (closed source) does this - just not sure how! I want to execvlp a new program but before doing so, redirect the new programs stdin, stdout and stderr fd's to the parent e.g. int newfdout = dup2(STDOUT, newfdout) But, from what I have read, you are not allowed to execute any code in the child once forked (well, vforked) for risk of corrupting the parent. Is there a way to exec a new program under uClinux but redirect the filedescriptors to the parent? The code above does not work. Any ideas? Apologies in advance if this is an obvious question. /M" <  Shutting down embedded linux. | Vote in the 2009 Embedded Linux survey  >		uCdot Login Nickname: Password: [ Create a new account ] Related Links uClinux prebbz More on Question Also by davidm

Basically, keep everything after the vfork as simple as possible, a few basic system calls is usually ok. Check this FAQ entry, uClinux for Linux Programmers [ucdot.org], should help you out.
