I'm trying to create a client socket to send a http request to a server, but an error is occurring in the function connect, in turn primeir returned this error: "connect: Socket operating on non-socket 'and' connect: no such file or directory 'I did not find anything wrong in my code so I went looking two examples of client sockets, and they tanbem returned this error.
my code is this:
Code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <netdb.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <arpa/inet.h>
char erro[80];
int host_para_ip(const char* host, char* ip);
int main(int argc, char* argv[])
{
int sock;
struct sockaddr_in addr;
int porta = 80;
char ip[16];
if(argc == 1)
{
printf("Argumentos inválidos.\n");
exit(1);
}
if(host_para_ip(argv[1], ip) == 1)
{
printf("Endereço inválido.\n");
return 1;
}
if((sock = socket(AF_INET, SOCK_STREAM, 0) < 0))
{
perror("socket");
return -1;
}
addr.sin_family = AF_INET;
addr.sin_port = htons(porta);
addr.sin_addr.s_addr = inet_addr(ip);
if(connect(sock, (struct sockaddr*)&addr, sizeof(addr)) < 0)
{
perror("connect");
return -1;
}
printf("Conectado!\n");
return 0;
}
int host_para_ip(const char* host, char* ip)
{
struct hostent* h = gethostbyname(host);
if(h == NULL)
{
return 1;
}
strcpy(ip, (char*)inet_ntoa(*((struct in_addr *)h->h_addr)));
return 0;
}
if anyone knows what is causing the error I am grateful.
