I tried to read the mac address in the captioned file path.
In terminal, I can simply 'cat' and display the mac address.
In FPC, when I tried to use TFileStream to read it,
FS := TFileStream.Create('/sys/class/net/eth1/address',
it raised "stream read error"
If I tried to use TextFile and readln, it even halted the program.
My question is:
Why 'cat' command can easily display this special file 'address' but
I was told to use this method to get the MAC address of a network card,
what other methods are there?
