I am porting a driver from another flavor UNIX to FreeBSD. The driver in =
questions uses 4 specific Kernel functions that I would appreciate =
someone giving me a little more info about than that which is contained =
in the manual.
The four are:
tsleep() - sleep() is used in the original driver
timeout()
untimeout()
wakeup()
All four are subtly different in arguments and return values from the =
form in FreeBSD. Further, due to ambigious documentation, they could =
work differently, or the same. If they effectively perform the same =
fuction, I can easily convert the code, if not I will have to rewrite =
the function or find some other work around. I perfer the former.
Any help would be appreciated.
Please reply to my work E-mail - bb@netwolves.com
Thanks in advance
Bill Britt
