Re: diff. bet sockaddr & sockaddr_in ?

[Sunil V <sunilv@xxxxxxxxxxxxxxx>]

Hello,
The definition of 'struct sockaddr' is in <sys/socket.h>.
This structure has a 14-byte protocol specific address which is 
interpreted based on type of address. For intenet family it is 
'struct sockaddr_in' defined in <netinet/in.h>

In simple words, 'struct sockaddr' is a generic socket structure and 
'struct sockaddr_in' is Internet socket address structure.

If this has confused you more, refer the book 'Unix Network Programming'
by W. Richard Stevens.
