linux 进程间通讯方法整理

一.无名管道pipe

 

#include <unistd.h>int pipe(int fd [2])

二.fifo

 

#include <sys/stat.h>int mkfifo(const char *path, mode_t mode);

三.信号

 

#include <signal.h>void (*signal(int sig, void (*func)(int)))(int);

 

#include <signal.h>int sigaction(int sig, const struct sigaction *restrict act,struct sigaction *restrict oact);

 

#include <signal.h>int kill(pid_t pid, int sig);

 

#include <signal.h>int raise(int sig); 

 

#include <signal.h>int sigqueue(pid_t pid, int signo, const union sigval value);

 

#include <unistd.h>unsigned alarm(unsigned seconds);

 

#include <stdlib.h>void abort(void);

 

四.消息队列

 

#include <sys/msg.h>int msgsnd(int msqid, const void *msgp, size_t msgsz, int msgflg);

 

#include <sys/msg.h>ssize_t msgrcv(int msqid, void *msgp, size_t msgsz, long msgtyp,int msgflg);

 

#include <sys/msg.h>int msgget(key_t key, int msgflg);

 

#include <sys/msg.h>int msgctl(int msqid, int cmd, struct msqid_ds *buf);

 

五.信号量

 

#include <sys/ipc.h>key_t ftok(const char *path, int id);

 

#include <sys/sem.h>int semget(key_t key, int nsems, int semflg);

 

#include <sys/sem.h>int semop(int semid, struct sembuf *sops, size_t nsops);

 

#include <sys/sem.h>int semctl(int semid, int semnum, int cmd, ...);

 

六.共享内存

 

#include <sys/shm.h>int shmget(key_t key, size_t size, int shmflg);

 

#include <sys/shm.h>void *shmat(int shmid, const void *shmaddr, int shmflg);

 

#include <sys/shm.h>int shmdt(const void *shmaddr);

 

#include <sys/shm.h>int shmctl(int shmid, int cmd, struct shmid_ds *buf);

 

七.socket

 

#include <sys/socket.h> int socket(int domain, int type, int protocol);

 

#include <sys/socket.h>int bind(int socket, const struct sockaddr *address,socklen_t address_len);

 

#include <sys/socket.h>int connect(int socket, const struct sockaddr *address,socklen_t address_len);

 

#include <sys/socket.h>int accept(int socket, struct sockaddr *restrict address,socklen_t *restrict address_len);

 

#include <sys/socket.h>ssize_t recv(int socket, void *buffer, size_t length, int flags);

 

#include <sys/socket.h> ssize_t recvfrom(int socket, void *restrict buffer, size_t length,int flags, struct sockaddr *restrict address,socklen_t *restrict address_len);

 

#include <sys/socket.h>ssize_t recvmsg(int socket, struct msghdr *message, int flags);

 

#include <sys/socket.h>ssize_t send(int socket, const void *buffer, size_t length, int flags);

 

#include <sys/socket.h>ssize_t sendto(int socket, const void *message, size_t length,int flags, const struct sockaddr *dest_addr,socklen_t dest_len);

 

#include <sys/socket.h>ssize_t sendmsg(int socket, const struct msghdr *message, int flags);
