Look at, compile, and run some of the examples from the textbook code
from chapter 8, which is at
Note that all the code in there needs csapp.c and csapp.h
in src/ and include/ respectively ... or we re-write and
search the docs to find out which C standard include files are needed.
See for example alarm2.c (attached) without the csapp stuff.
alarm.c
shellex.c
sigint1.c
signal1.c # queing issues with signals
signal2.c
signal3.c
signal4.c
procmask1.c # race conditions
procmask2.c
... and any others that strike our fancy. (Fork bombs, anyone?)
I've posted an assignment for next week on this stuff.
If time allows, also look at practice problems 8.5, 8.6, 8.7 (they all go together):
write a program snooze.c that takes a command line argument
and the reports on how long until the user types control-C .
$ ./snooze 10
Slept for 3 of 10 seconds. # user typed control-C
(The answers to all three are in the text ... though it
will as usual here take some reading of docs to figure
out which .h files we need to include.)
