This is silly. Sockets are defined as a C API, and "later languages" have to make all those C calls at some level.

Nettet7. feb. 2024 · It’s based on the path the socket is bound to or connecting to, as specified in the `bind` or `connect` syscall. If the Unix socket path is a DrvFS path (i.e your system volumes mounted within WSL, ex: /mnt/c, /mnt/d etc.) then it can only communicate to a Windows Unix socket. NettetIn POSIX C programs, if read() attempts to read from an empty pipe or a FIFO special file, it has one of the following results: If no process has the pipe open for writing, read() returns 0 to indicate the end of the file. If some process has the pipe open for writing and O_NONBLOCK is set to 1, read() returns -1 and sets errno to EAGAIN.
