THANX !!!
Kelam_Magnus
Well i am surely serious about my question; like I am always looking for logical reasons to clear my doubts & questions thats why I have put up this question. after taking a look at the long history of UNIX OS's......there no time to even compare all of them in any regards
...your reply has given me now a clear concept of what are the unix flavors all about & why its not possible to give all the credits to just one flavor. thanx again.
J.P
Thanx for the advice as most people including you are recommending BSD's/Slackware/redhat.......thats why i am starting with Free BSD; about linux....i have been using red hat linux7x from last 6 months but i feel to shift to unix as in my country many students almost all are trying to go for linux.....certs etc everywhere I listen is linux over here...but a very few even know about the capabilities of unix.....may be thats why I feel it like when i am going to complete my graduation.....there will be a lot of people knowing linux but a very few to admin unix boxes. and i always want to go for something which is different.
Neo
Yes indeed; one cannot have all the flavors available at the icecream palor at the same time; it all depends on individual liking...
& its gonna take a long time to taste em' all. Since I am new to this world of ICECREAM flavors; i don't know how they taste;...whether i m' gonna like vanila or strawberry....but its very nice of all of you out there to help me narrow my choices among the large number of flavors. thanx Neo.
It was my very first thread @ unix.com & thanx to all of you for your nice & kind suggestions; I feel it that now @ unix.com I am gonna have a superb time learning UNIX OS's with all you nice fellows helping around. thanx again everyone!
Regards,
MGA

getpeereid
GETPEEREID(3) BSD Library Functions Manual GETPEEREID(3)
NAME
getpeereid -- get the effective credentials of a UNIX-domain peer
LIBRARY
Utility functions from BSD systems (libbsd, -lbsd)
SYNOPSIS
#include <sys/types.h>
#include <bsd/unistd.h>
int
getpeereid(int s, uid_t *euid, gid_t *egid);
DESCRIPTION
The getpeereid() function returns the effective user and group IDs of the peer connected to a UNIX-domain socket. The argument s must be a
UNIX-domain socket (unix(4)) of type SOCK_STREAM on which either connect(2) or listen(2) have been called. The effective used ID is placed
in euid, and the effective group ID in egid.
The credentials returned to the listen(2) caller are those of its peer at the time it called connect(2); the credentials returned to the
connect(2) caller are those of its peer at the time it called listen(2). This mechanism is reliable; there is no way for either side to
influence the credentials returned to its peer except by calling the appropriate system call (i.e., either connect(2) or listen(2)) under
different effective credentials.
One common use of this routine is for a UNIX-domain server to verify the credentials of its client. Likewise, the client can verify the cre-
dentials of the server.
IMPLEMENTATION NOTES
On FreeBSD, getpeereid() is implemented in terms of the LOCAL_PEERCRED unix(4) socket option.
RETURN VALUES
The getpeereid() function returns the value 0 if successful; otherwise the value -1 is returned and the global variable errno is set to indi-
cate the error.
ERRORS
The getpeereid() function fails if:
[EBADF] The argument s is not a valid descriptor.
[ENOTSOCK] The argument s is a file, not a socket.
[ENOTCONN] The argument s does not refer to a socket on which connect(2) or listen(2) have been called.
[EINVAL] The argument s does not refer to a socket of type SOCK_STREAM, or the kernel returned invalid data.
SEE ALSO
connect(2), getpeername(2), getsockname(2), getsockopt(2), listen(2), unix(4)
HISTORY
The getpeereid() function appeared in FreeBSD 4.6.
