OK so i tried doing some simple socket programming....however am I right in assuming that I will have to use the MicroC/OS-II structure...
I have tried the following code, but Nios II IDE can't find the ipport.h and tcpport.h files, which contain all the socket programming fucntions...
# include "sys/socket.h"
# include <unistd.h>
# include <string.h>
# include <alt_types.h>
# include <ctype.h>
# include <errno.h>
# include <stdio.h>
# include <sys/alt_flash.h>
# include "includes.h"
# include "io.h"
# include "ipport.h"
# include "tcpport.h"
# include "network_utilities.h"
# define LOCAL_SERVER_PORT 1500
# define SERVER_PORT 1500
# define MAX_MSG 100
int main (int argc, char *argv[]) {
int sd, rc, i;
struct sockaddr_in localAddr, servAddr;
struct hostent *h;
if(argc < 3) {
printf("usage: %s <server> <data1> <data2> ... <dataN>\n",argv[0]);
exit(1);
}
h = gethostbyname(argv[1]);
if(h==NULL) {
printf("%s: unknown host '%s'\n",argv[0],argv[1]);
exit(1);
}
servAddr.sin_family = h->h_addrtype;
memcpy((char *) &servAddr.sin_addr.s_addr, h->h_addr_list[0], h->h_length);
servAddr.sin_port = htons(SERVER_PORT);
/* create socket */
sd = socket(AF_INET, SOCK_STREAM, 0);
if(sd<0) {
perror("cannot open socket ");
exit(1);
}
/* bind any port number */
localAddr.sin_family = AF_INET;
localAddr.sin_addr.s_addr = htonl(INADDR_ANY);
localAddr.sin_port = htons(0);
rc = bind(sd, (struct sockaddr *) &localAddr, sizeof(localAddr));
if(rc<0) {
printf("%s: cannot bind port TCP %u\n",argv[0],SERVER_PORT);
perror("error ");
exit(1);
}
/* connect to server */
rc = connect(sd, (struct sockaddr *) &servAddr, sizeof(servAddr));
if(rc<0) {
perror("cannot connect ");
exit(1);
}
for(i=2;i<argc;i++) {
rc = send(sd, argv
, strlen(argv) + 1, 0);
if(rc<0) {
perror("cannot send data ");
close(sd);
exit(1);
}
printf("%s: data%u sent (%s)\n",argv[0],i-1,argv[i]);
}
return 0;
}
