First, i know java well and i have used C++ on occasion so i thought i would be able to deal with a class where they program in C. unfortunately i have hit some speed bumps that i am having problems.
Here is my problem:
I have a structure cache_t in the sample program we are supposed to use. In one of my functions i am supposed to use a pointer to an instance of this cache_t struct to perform some operations and return a value.
How do i get the value of nsets? i have tried &cp.nsets but that just gives me an error:
error: request for member 'nsets' in something not a structure or union

ah, nevermind. As i guessed it was my inexperience with C causing problems. I was looking for cp->nsets.

iv_inotify
iv_inotify(3) ivykis programmer's manual iv_inotify(3)NAME
IV_INOTIFY_INIT, iv_inotify_register, iv_inotify_unregister, IV_INOTIFY_WATCH_INIT, iv_inotify_watch_register, iv_inotify_watch_unregister
- ivykis inotify(7) wrapper
SYNOPSIS
#include <iv_inotify.h>
struct iv_inotify {
};
void IV_INOTIFY_INIT(struct iv_inotify *inotify);
int iv_inotify_register(struct iv_inotify *inotify);
void iv_inotify_unregister(struct iv_inotify *inotify);
struct iv_inotify_watch {
struct iv_inotify *inotify;
const char *pathname;
uint32_t mask;
void *cookie;
void (*handler)(void *, struct inotify_event *);
};
void IV_INOTIFY_WATCH_INIT(struct iv_inotify_watch *watch);
int iv_inotify_watch_register(struct iv_inotify_watch *watch);
int iv_inotify_watch_unregister(struct iv_inotify_watch *watch);
DESCRIPTION
The iv_inotify_register function registers an iv_inotify instance with the iv_inotify(3) module. The inotify parameter is a pointer to the
iv_inotify structure to be registered.
The iv_inotify_unregister function unregisters an iv_inotify instance from the iv_inotify(3) module. The inotify parameter is a pointer to
the iv_inotify structure to be unregistered.
The iv_inotify_watch_register function adds a watch to the registered iv_inotify instance specified by the ->inotify member.
The iv_inotify_watch_unregister function removes a watch from the iv_inotify instance specified by the ->inotify member.
In the iv_inotify_watch structure used in these functions, the ->pathname and ->mask members correspond to the members of struct ino-
tify_watch as described in inotify(7). ->handler is the event handler called when this watch triggers. The arguments to this handler
function are the pointer stored in the ->cookie member of the iv_inotify_watch structure and a pointer to an inotify_event structure as
described in inotify(7).
RETURN VALUE
iv_inotify_register and iv_inotify_watch_register return zero on success. On error, -1 is returned, and errno is set appropriately.
ERRORS
iv_inotify will return errors returned by inotify_init(3) and inotify_add_watch(3).
