Hi,

Thanks for the message. I have done exactly as u told me. But my testt program still fails. The program is:

//-----

#include <stdio.h>
#include <stdlib.h>
#include <errno.h>
#include <string.h>
#include <sys/types.h>
#include <netinet/in.h>
#include <sys/socket.h>
#include <sys/wait.h>
#include <sctp.h>
#include <ext_socket.h>
//#include <netinet/sctp_uio.h>

main()
{
int fd,ret,newfd;
struct sockaddr_in s, who;
fd=ext_socket(PF_INET,SOCK_STREAM,IPPROTO_SCTP);
if(fd<0)
{
printf("Socket Failed\n");
exit(1);
}

printf("I am fine here\n");

}//end main

//------

and it gives me this error(recognizing the files but not the "ext_socket"call) when compiled with

gcc -o tes testprogram.c -lsctp -lglib

//--error--*********************

tmp/cc8jlr35.o(.text+0x1d): In function `main':
: undefined reference to `ext_socket'
collect2: ld returned 1 exit status

//--------***********************

please let me know where I am goin wrong. If it is recognizing the ".h"file then why is it not taking the ext_socket call then. very much confused about this. help me out.Thanks.

Hi,

first of all you DO need root previledges for all programs.

The sctplib provides an SCTP implementation using a call-back
API. See the examples directory within the tarball for examples.

To use the socketAPI you must also download and install the
socketapilib.

Then you can use the socketapi, but you must use
ext_socket instead of socket,
ext_bind instead of bind
and so on. Please see the examples in the socket_examples directory.

Best regards
Michael
