Re: advanced programming unix environment
Hi Mel,
Thanks for your reply - very insightful - i have beendelving into the c library
files - which is after all why i am readingthis book, though still at the
beginning 8).
On the pracct.c source file I have found it sufficient just to change line 31
from
struct acctacdata;
to
struct acctv1acdata;
this leaves me with only 1 error which I have side stepped but not fixed.
error: +
bsdexit2.c: In function 'thr_fn2';
bsdexit2.c:31: Warning format '%d' expects type 'int', but argument 2 has type
'pthread_t'
+
line 31of threads/bsdexit2.c reads:
printf("thread 2: ID is %d\n", pthread_self
which I have commented this line and Make finishes building.
however which "% ?" operater would I use to display pthread_self.
In the c library pthread.h it says it is of "pthread_t" type.
I appreciate your help and I am grateful that you have inspired me.
Kindest regards,
Seamus

The legacy struct acct has been renamed to acctv1 and a new one is named
acctv2.
If you add:
typedef struct acctv1 acct_t;
After the #include
then change the type of acdata to 'acct_t', you'll probably have solved it.
But depends a bit on the rest of the library.

Problem with today's modular software: they start with the modules
and never get to the software part.

Re: advanced programming unix environment
just a note: same source code makes fine on solaris installation.
I would appreciate if somebody else running freebsd 7.0 could download source
and see if it makes fine on their installation.
Steven's "Advance Programming in the Unix Environment" Source code:
