socket的操作集为
struct proto_ops {
int family;
int (*release) (struct socket *sock);
int (*bind) (struct socket *sock, struct sockaddr *umyaddr, int sockaddr_len);
int (*connect) (struct socket *sock, struct sockaddr *uservaddr, int sockaddr_len, int flags);
int (*socketpair) (struct socket *sock1, struct socket *sock2);
int (*accept) (struct socket *sock, struct socket *newsock, int flags);
int (*getname) (struct socket *sock, struct sockaddr *uaddr, int *usockaddr_len, int peer);
unsigned int (*poll) (struct file *file, struct socket *sock, struct poll_table_struct *wait);
int (*ioctl) (struct socket *sock, unsigned int cmd, unsigned long arg);
int (*listen) (struct socket *sock, int len);
int (*shutdown) (struct socket *sock, int flags);
int (*setsockopt) (struct socket *sock, int level, int optname, char *optval, int optlen);
int (*getsockopt) (struct socket *sock, int level, int optname, char *optval, int *optlen);
int (*sendmsg) (struct socket *sock, struct msghdr *m, int total_len, struct scm_cookie *scm);
int (*recvmsg) (struct socket *sock, struct msghdr *m, int total_len, int flags, struct scm_cookie *scm);
int (*mmap) (struct file *file, struct socket *sock, struct vm_area_struct * vma);
ssize_t (*sendpage) (struct socket *sock, struct page *page, int offset, size_t size, int flags);
};
而qnx中资源管理器提供的connet和io操作集是
typedef struct _resmgr_connect_funcs {
unsigned nfuncs;
int (*open)(resmgr_context_t *ctp, io_open_t *msg, RESMGR_HANDLE_T *handle, void *extra);

int (*power)(resmgr_context_t *ctp, io_power_t *msg, RESMGR_OCB_T *ocb);
} resmgr_io_funcs_t;
2个好像有部分对应不上？
