Hola, q tal? despues de compilar el codigo de ejemplo del programa cliente/servidor del primero tutorial... me compila bien el cliente, pero el servidor no. Este es el codigo:
 
--- Código: Text --- #include <stdio.h>#include <sys/types.h>#include <sys/socket.h>#include <netinet/in.h>#include <netdb.h> #include <sys/param.h>  #include <errno.h> #define ERROR(s)       {fprintf(stderr,"%d-",errno); perror(s); return(-1);} main (argc, argv)int argc;char *argv[];{    struct sockaddr_in sa;      struct sockaddr_in caller;     int s, msgsock, length;    int retval;    char buf[BUFSIZ], acknowledgement[BUFSIZ];       if ((s = socket(AF_INET,SOCK_STREAM,0)) < 0)          ERROR ("socket");     /* name socket, register the socket */    sa.sin_family= AF_INET;            sa.sin_addr.s_addr = INADDR_ANY;       /* not choosy about who calls */        sa.sin_port= 22222;                   /* this is our port number */         if (bind(s,(struct sockaddr_in *)&sa,sizeof sa) < 0)                ERROR ("bind");                 /* bind address to socket */     /* get assigned port number and print it */    length = sizeof(sa);        if (getsockname(s, (struct sockaddr_in *)&sa, &length) < 0)                ERROR("getsockname");        /* listen for connections on a socket */    listen (s, 5);     /* Use accept to wait for calls to the socket.  Accept returns    a new socket which is connected to the caller.  msgsock will be a        temporary (non-resuable) socket different from s */    if ((msgsock = accept(s,(struct sockaddr *)&caller,&length)) < 0)            ERROR ("accept");      /* optional ack; demonstrates bidirectionality */    gethostname(buf, sizeof buf);     /* write into the msgsock; the "s" is _only_for_rendezvous_ */    if ( write ( msgsock, acknowledgement, sizeof acknowledgement ) < 1 )        perror(argv[0]);      /* read lines until the stream closes */     retval = 1;    while(retval !=0 )  {        bzero(buf, sizeof(buf));         if( (retval = read(msgsock, buf, sizeof(buf))) < 0)                perror("reading stream message");    if (retval == 0) printf("ending connectionn");        else  printf("read-->%sn", buf);     }     close(msgsock);    close (s);     exit (0);}  
El error que me da es este:
 
--- Código: Text --- $ gcc server.c -o serverserver.c: In function `main':server.c:33: warning: passing arg 2 of `bind' from incompatible pointer typeserver.c:38: warning: passing arg 2 of `getsockname' from incompatible pointer type  Sabeis porque puede ser? Gracias

joaquinrg:
bueno, me confundio, no es el de chuidiang,  pero ahora lo comparo con el suyo a ver si encuentro cual es el error

joaquinrg:
solucionado, en vez de poner sockaddr_in habia q poner solo sockaddr
