socketI implementation

socketI implementation

[sting sting]

Hello,

I had downloaded the tar.gz of glibc;
I
I am interested in the learning the network layer and
implementation of  the socket API in glibc
(calls like socket,bind,gethostbyname,etc.).
I saw in the inet subdirectory on glibc that it seems that  these calls
are eventually result in calls to methods in nss subdirectory.

But I am not sure.
Am I right in my assumption?
or where I can find the implementation of methods like bind(), connect(), 
socket(), etc.

regards
sting

Wrong list. However, the interface to the network through the
kernel is __NR_socketcall (function 102).
You need to learn how to use `find`, `grep` and other Unix
tools to search large directory trees like glibc.
For instance, in glibc-2.3.1, a lot of utility functions
are in glibc-2.3.1/inet and a lot of socket interface code
is in glibc-2.3.1/unix/sysv/linux/i386/socket.S
