Need some specific OS method

[Samprayoga]

Hello,

I would like to have the name of C++ Unix methods that allow to:
- get the system date,
- get the user login name,
- get the IP address,
- get the serial number of the network card,
- get the host ID.

Thanks for help.

S.

1. time() and localtime() together will give you the system date (as part of the tm structure returned from localtime).

2. gethostname() will give you the hostname of the system.

3. gethostbyname() returns a hostent structure that includes the address(es) of the host.

4. There is a function to get the username, but I forget what it is.

5. The SERIAL number of a NIC? Well, if it's PCI, there are functions (in Linux at least) that let you read the PCI configuration space...it might be there...
