I am trying to figure the usage of
int atnotify(int (*f)(void *, char *), int in);
to set up an alarm signal hendler. I can't get past the type mismatch
error. Any pointers will be appreciated. The sample code is given below.

#include <u.h>
#include <libc.h>
int handle(void *uureg, char *signal)
{
print("signal seen: %s\n", signal);
return 1;
}
main()
{
char *reason="alarm";
atnotify(handle(nil, reason), 1);
alarm(1000);
print("All done..\n");
exits(0);
}

remove ^^^^^^^^^^^^^ you want the function name, not a
call to it.
