Subject: [9fans] Questions about libthread and setjmp
Date: Mon, 21 Feb 2005 13:15:15 +0100 [thread overview]
Message-ID: <afb1cac24a379c0512ee89a9058fcc50@plan9.escet.urjc.es> (raw)
I have some questions regarding the man pages of setjmp
and the thread library implementation (the commentaries).
In setjmp(2):
The commentary "-2 leaves room for old pc and new pc in frame"
in the setlabel definition (there is also a missing bracket
in label[JMPBUFSP but that is another story).
What does it mean?. I simply don't understand it. Maybe I am
missing something...
There is another strange commentary too in the same fashion.
Probably for the same reason I don't understand the first one
I don't understand this one.
t->sched[JMPBUFSP] = (ulong)tos - 8; /* old PC and new PC */
Can anyone explain please?.
G.
