Nu cred ca dpdv al aplicatiei te intereseaza cum e implementat epoll. Tu
foloseste API-ul oferit (epoll_create, epoll_ctl, epoll_wait) si lasa-l
pe glibc sa-si bata capul cu detaliile implementarii.

Se pare ca nu (btw, 2.4.21-37-EL e update 6):
[EMAIL PROTECTED] tmp]$ cat epoll.c
#include <unistd.h>
#include <sys/epoll.h>
int main()
{
epoll_create(100);
return 0;
}
[EMAIL PROTECTED] tmp]$ cat /etc/redhat-release
Red Hat Enterprise Linux AS release 3 (Taroon Update 5)
[EMAIL PROTECTED] tmp]$ uname -r
2.4.21-32.ELsmp
[EMAIL PROTECTED] tmp]$ strace ./a.out 2>&1 | grep epoll
epoll_create(100) = -1 ENOSYS (Function not
implemented)
[EMAIL PROTECTED] tmp]# cat /etc/redhat-release
Red Hat Enterprise Linux AS release 3 (Taroon Update 6)
[EMAIL PROTECTED] tmp]# uname -r
2.4.21-37.ELsmp
[EMAIL PROTECTED] tmp]# strace ./a.out 2>&1 | grep epoll
epoll_create(100) = -1 ENOSYS (Function not
implemented)
