I can tell you offhand that _thread_sys_anything is the _real_ syscall for `anything'. This is because a lot of syscalls are reimplemented within libc_r for reasons that are kind of obvious (directly calling the read syscall from one thread would block all the other threads in a process). So _thread_sys_open() == open(2), _thread_sys_read() == read(2), etc. I don't know about pci_intr_establish. -- |Chris Costello <chris@calldei.com> |Today's assembler command : EXOP Execute Operator `---------------------------------------------------- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
