Thread: Creating RDM sockets

I tried to create an RDM socket in this manner :

Code:

    if ((sockfd = socket(AF_INET, SOCK_RDM, 0)) == -1) {
            perror("socket");
            exit(1);
        }

But, i got the following error message :

Code:

  socket: Socket type not supported

If I replace SOCK_RDM with SOCK_DGRAM, the program runs as expected.
These are the included header files :

Code:

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

Do i have to include any other file to create an RDM socket?

I seem to have the same problem even with SEQPACKET.

It turns out AF_INET does not support the two protocols ....
