Got the poll function working , but now it only lasts a little bit longer , still dies :(

Btw i just ran
file on the program

ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.2.5, stripped

Ok i re-read your whole posts .. i will give you this i am over my head ..but can you help ? what FACTS would you like me to share ? i can share my screen with you on teamviewer if that helps ?

What i am basically doing is not wrapping poll , and calling poll from poll again , so it gets called a few hundred times before i kill the program
so i know its getting called
i hope i am able to...

#include <poll.h>
#include <unistd.h>
#include <stdio.h>
int poll(struct pollfd *fds, nfds_t nfds, int timeout) {
usleep(100);
printf("Sleeping\n");
return poll(fds,nfds,timeout);...

It compiles without error but my poll is not getting called
1. Preload works as i have tested it with removing wrap, then it gets into the function ( tested by adding a printf )

I need to wrap poll()
and this is what i am trying to use


#include <poll.h>
#include <unistd.h>
#include <sys/types.h>


int __wrap_poll(struct pollfd *fds, nfds_t nfds, int timeout) {

hey
I dont get any errors
and when i preload it with ld_preload , it does load
i check it with LD_PRELOAD=/home/poll.so ldd ./program
but the program is not using my version of the poll

can someone tell me my mistake in this ?



#include <poll.h>
#include <stdio.h>
#include <unistd.h>


int __wrap_poll(struct pollfd *fds, nfds_t nfds, int timeout) {

Update: I can sun 2 copies just fine
but another 2 dont work

Ok another interesting thing , hope i dont jinx it , 2 copies are running fine of the same program with same timer.so loaded and 2 keep crashing

btw the file its trying to open i think is a socket that it uses to communicate with the other copy of the program
basically you run 4 copies and they send stuff to each other by opening a socket in...

btw there is no corefile

Thanx but my doubt is
1. when i added printf to empty gettime
i DO get the *s printed on my screen
2. is it possible that it , like you say , loads the new gettime
and original gettime ,
but...

so salem can you help me with the code for what i have in mind ?

gettimeofday()
if called first time , return correct time , store in variable
after being called 2nd to 20 or 30 or...

when i give it return 0 for gettimeofday ( empty function just returns 0)
then it gets stuck at


t_sigprocmask(SIG_UNBLOCK, [ALRM], NULL, 8) = 0
poll([{fd=4, events=POLLIN}, {fd=6,...

i increased it to 500
and still no luck



rt_sigprocmask(SIG_BLOCK, [ALRM], NULL, 8) = 0
gettimeofday({1348140798, 56749}, NULL) = 0
rt_sigprocmask(SIG_UNBLOCK, [ALRM], NULL, 8) = 0...

I have it running the new poll and its dumping core and strace is being written faster

nope dumped core

I am testing it now
but in the meantime if this does not work
this is what i was thinking

have a counter written to a file first time gettimeofday is called
let it get the right time 20 times(...

strace is writing about 15mb a second with this
is that normal :)

Dammit spoke too soon :(
Core dumped
well it ran for a whole 10 mins longer than before thats a good sign

[QUOTE=NetworkLearning;1123684]Salem,
are you still here
OK i have the program reading my version ( or your version ) of gettimeday but does not seem to be doing anything tho ?

maybe throttle...
