question about _exit() function

Hi, is the _exit() function safe for a thread ? my program use vfork() and then execve in a thread context. The documentation mentions that the process has to call _exit() in case of failure. But this _exit() is really safe for the parent thread ? Thanks in advance for the reply.

fopen() on a pipe blocks multi threated applications.

Hi fopen() on a pipe blocks multi threated applications. If pipe is not ready for reading, fopen blocks every thread until STREAM is ready. Is there a good reason for this ? Regards [EMAIL PROTECTED] ___ [EMAIL PROTECTED] mailing list http://lists.fr
