Thanks so much.
Have never worked with Perl before and downloaded tutorial to help me understand the syntax. Would you suggest a good book on it?
This code was awesome. The input file does consist of lots more information and the task tag has about 2 dozen attributes. (This is an embedded software file created by another integrator and has about 1000 tasks in it with multiple tags underneath). I do software code checking as code changes, this whole file was being recreated. Now all that has to be done is change the task xml file and re-imbed it. Magic..
The xml code is on an intranet machine and cannot be copied from, so the file and problem was abbreviated for convenience.
The only problem was
(m/id="(.*)"/)
actually captured the whole line including other attributes.
Each task is defined by the same version number appended to the end. I got the correct name by adding
(m/id="(.*)VERS5"/).
The last part was not captured, but it did end there. I tried the
(m/s/id="(.*)VERS5"/)
but it did not work. I got what I wanted by doing the perl then
ls *.xml > temp1
sed -e "s|.xml||g" temp1 > temp2
cat temp2 |xargs -n 1| while read TASKNAME
do
mv $TASKNAME.xml $TASKNAME'Vers5.xml'
done
This is the first time I have worked with Sun workstations and don't have this scripting thing down but with the help of this website, I have been able to do lots of neat things which have saved time.
Thanks all, this site is fantastic.
PS I am thinking about getting a MAC now that I am starting to understand UNIX. Any suggestions on what I should get?
Thanks again,
MissI

iv_task_unregister
iv_task(3) ivykis programmer's manual iv_task(3)
NAME
iv_task_register, iv_task_unregister, iv_task_registered - deal with ivykis tasks
SYNOPSIS
#include <iv.h>
struct iv_task {
void *cookie;
void (*handler)(void *);
};
void IV_TASK_INIT(struct iv_task *task);
void iv_task_register(struct iv_task *task);
void iv_task_unregister(struct iv_task *task);
int iv_task_registered(struct iv_task *task);
DESCRIPTION
The functions iv_task_register and iv_task_unregister register, respectively unregister, a task with the current thread's ivykis event
loop. iv_task_registered on a task returns true if that task is currently registered with ivykis.
A task is like a timer, but with an immediate timeout. When a task is registered, unless it is unregistered again first, the callback
function specified by ->handler is guaranteed to be called once, in the thread that the task was registered in, some time after control
returns to the ivykis main loop but before ivykis will sleep for more events, with ->cookie as its first and sole argument. When this hap-
pens, the task is transparently unregistered.
Tasks are mainly used for scheduling code for execution where it is not appropriate to directly run that code in the calling context (for
example, because the current context might be run as a callback function where the caller expects certain conditions to remain invariant
after the callback completes).
The application is allowed to change the ->cookie and ->handler members at any time.
A given struct iv_task can only be registered in one thread at a time, and a task can only be unregistered in the thread that it was regis-
tered from.
There is no limit on the number of tasks registered at once.
See iv_examples(3) for programming examples.
