Use Posix function:
timer_create
timer_settime
etc.

i was looking into butenhof's programming with posix threads book for
timer_create
and timer_settime. I tried to compile the code given in the book but
its showing undefined refernce to timer_create and timer_settime.

the header files used in the code are :

#include
#include
#include

in my Makefile i am providing the link path for pthread library as
follows:
-L/usr/lib -pthread which is correct i suppose.

where are these functions timer_create() and timer_settime() defined?

i have got to get the things work...........i added -lrt in the link
path.
Thanks Bin

Hi,
I am enjoying my work with timers and its quite interesting, though at
times giving me tough time.

How to pass a parameter (integer type) to the thread function which is
called at timeout of the timer.
any sample code will be extremely helpful for me.

thanks
