libipc/TODO.md

misc

• create the unix socket directory
• close the connection and log when we receive too big messages
• decide then explicitely document what the max message size should be
• rx message buffer should be small but should grow if required
• some functions are not exposed in the bindings, mostly functions related to switching

makefile

• release
• distribution

documentation

• document the two ways to use LibIPC: either within some Zig code or through the bindings
• manpages for ipcd, tcpd, pong, pongd

src/exchange-fd.zig

• still very WIP, even though it works as expected
• recvmsg is a very stupid copy of the sendmsg fn, EXPECT ERRORS (if used outside libipc)
• at least one memory error when using Cmsghdr (see below)
