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
