Hi,

I am using Sun Solaris Forte Compiler 7 using c++ compiler.

I need some help to understand the error I am geting when I use bind in my code.
It is failing with an error number 124 which does not explain in the man bind page.
The bind function is called as follows.(all code attached below)

Status = bind(
SockFd,
(struct sockaddr *) &SockAddr,
sizeof ( SockAddr ) );

The return value of Status is -1.

When I print the errno(system) I get 124.
errno = 124
This error :"Address family not supported by protocol family"
What does this means!!!!!!!!Help!

Following is my diagnostic print statements output

These values are passed to bind call.
SockFd =3,
&SockAddr = 0x454ba,
sizeof(SockAddr) = 16

The bind call internally set these parameters which I printed for diagnostic as described in the man page.
eacces = 13
eio = 5
eisdir = 21
eaddrinuse = 125
eaddrnotavial = 126
ebadf = 9
einval = 22
enosr = 63
enosock = 95
eloop = 90
enoent = 2
enotdir = 20
erofs = 30

The C++ socket open code, it is failing at bind call.
