vxworks socket

VxWorks is a real-time operating system (RTOS) commonly used in embedded systems. It provides support for socket programming, allowing applications to communicate over network protocols such as TCP/IP and UDP.

To use sockets in VxWorks, you typically need to include the appropriate header files and link against the necessary libraries. The VxWorks API for socket programming is similar to the BSD socket API.

Here's a basic example of creating a socket in VxWorks:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <netinet/in.h>
#include <arpa/inet.h>
#include <sys/types.h>
#include <sys/socket.h>

#define PORT 1234

int main() {
    int sockfd;
    struct sockaddr_in server_addr;

    // Create socket
    sockfd = socket(AF_INET, SOCK_STREAM, 0);
    if (sockfd < 0) {
        perror("socket");
        exit(EXIT_FAILURE);
    }

    // Set server address
    memset(&server_addr, 0, sizeof(server_addr));
    server_addr.sin_family = AF_INET;
    server_addr.sin_port = htons(PORT);
    server_addr.sin_addr.s_addr = inet_addr("127.0.0.1");

    // Connect to server
    if (connect(sockfd, (struct sockaddr *)&server_addr, sizeof(server_addr)) < 0) {
        perror("connect");
        exit(EXIT_FAILURE);
    }

    // Send and receive data...

    // Close socket
    close(sockfd);

    return 0;
}

This example demonstrates how to create a TCP socket, set the server address, establish a connection, and then close the socket. You can modify it according to your specific needs.

Please note that this is just a basic example, and there are many more functions and options available for socket programming in VxWorks. You can refer to the VxWorks documentation or specific guides for more detailed information.
