brapru 342e1f0a84 Kernel: Properly implement SO_ERROR option
This fixes the placeholder stub for the SO_ERROR via getsockopt. It
leverages the m_so_error value that each socket maintains. The SO_ERROR
option obtains and then clears this field, which is useful when checking
for errors that occur between socket calls. This uses an integer value
to return the SO_ERROR status.

Resolves #146

SerenityOS

Graphical Unix-like operating system for x86 computers.

About

SerenityOS is a love letter to '90s user interfaces with a custom Unix-like core. It flatters with sincerity by stealing beautiful ideas from various other systems.

Roughly speaking, the goal is a marriage between the aesthetic of late-1990s productivity software and the power-user accessibility of late-2000s *nix. This is a system by us, for us, based on the things we like.

I (Andreas) regularly post raw hacking sessions and demos on my YouTube channel.

Sometimes I write about the system on my github.io blog.

I'm also on Patreon and GitHub Sponsors if you would like to show some support that way.
