Support to XTI interface

[Harrison, Phil]

How do I go about getting a change to the core code to support the XT
interface?

 

Below are the changes I've made (connection only paradigm). I know is this
only half a job but is enough to get me going and allow integration with my
app.

 

To e_os.h 

 

#if defined(XTI)

#include <sys/tiuser.h>

#define get_last_socket_error() t_errno

#define clear_socket_error()    t_errno=0

#define closesocket(s)          t_close(s)

#define readsocket(s,b,n)       XTI_t_rcv(s,b,n,0)

#define writesocket(s,b,n)      t_snd(s,b,n,0)

#define ioctlsocket(a,b,c)      XTI_t_ioctl((a),(b),(int)(c))

#else

#if defined(WINDOWS)

.....

 

and the supporting code:

 

#include <stdio.h>

#include <errno.h>

#include <ctype.h>

#include <fcntl.h>

 

#include <poll.h>

#include <sys/tiuser.h>

 

static int waitforsomething(int fd)

{

        int numevents=0;

        struct pollfd fds[1];

 

        fds[0].fd       = fd;

        fds[0].events   = POLLIN | POLLPRI;

        fds[0].revents  = 0;

 

        while ((numevents = poll(fds, 1, -1)) == -1 )

        {

                if (errno != EINTR)  return -1;

        }

        return numevents;

}

 

int XTI_t_ioctl(int fd, int cmd, int pbuff)

{

        return -1;

}

 

int XTI_t_rcv(int fd, char *buf, unsigned nbytes, int *flags)

{

        int osievent = 0;

        int readflags=0;

 

        waitforsomething(fd);

        osievent = t_look(fd);

 

        switch (osievent)

        {

        case T_DATA: break;

        default: return -1;

        }

 

        readflags=O_NONBLOCK;

        return t_rcv(fd, buf, nbytes, &readflags);

}

 

Regards
