The exit() function does two things, closes all file descriptors
and then exits:
exit(n)
{
_cleanup();
_exit(n);
}
make sure you get the _cleanup() in your Exit() routine.
|Yesterday I was able to figure out a trick to overcome the exits
|present in GRASS:
|
|I created my own function called exit() which does nothing, and
|when the program is linked, this function is called, instead of
|the "real" exit. In my program, I now use a call to another
|function (Exit()) which merely calls _exit() when I want to get
|out.
|
|This gets around the calls to exit in the GRASS library, and
|still allows my program to exit when it wants.
