Hi there,
I retrieved bsd src files from ftp.uu.net (directory is
pub/OS/bsd-sources). What I need is the part dealing with the buffer
management. According to the book by Leffler et al, ie, "The design and
implementation of the 4.3BSD UNIX OS", the buffer cache (between the
file system and block device drivers) is initialized by the startup()
routine, and startup() is called in the main(). But I just could not
locate the startup() routine. Is startup() == cpu_startup(), the latter
is called in main() (I couldn't find the definition of cpu_startup()
either). Or is it written in assembly? Any suggestion would be welcome.
Thanx in advance! PLEASE RESPOND BY EMAIL at zaichunl@cs.tamu.edu.

PS: main() is located in file init_main.c in directory
pub/OS/bsd-sources/sys/kern.
