When I type "exit" on IOC shell, I would like to call a particular function
to return system resource and then want to terminate the IOC. Is there any
mechanism to register the particular function?
If you are using Base R3.14.7 or later, there is a facility in libCom
that you can use:
void epicsAtExit((*epicsExitFunc)(void *arg), void *arg);
You use it like this:
#include "epicsExit.h"
void myExit(void *myptr) {
/* my cleanup code */
}
...
epicsAtExit(myExit, (void *)myptr);
...
When the IOC exits, the myExit routine will be called with myptr as its
argument, which allows you to register the same routine several times
with different pointers if you wish (you can always pass in NULL if you
don't need a context pointer at all).
If your code has to work on an earlier version of Base though, Mark
Rivers' solution is your best bet.
