The network support in Cygwin is supposed to provide the POSIX API, not the Winsock API. There are differences between the semantics of functions with the same name under the API. E.g., the POSIX select system call can wait on a standard file handles and handles to sockets. The select call in Winsock can only wait on sockets.

Sep 24, 2018 · Cygwin is a POSIX compatibility layer that runs on top of the Win32 subsystem. It has approximately nothing to do with Linux; it can broadly be treated as "just another Unix-like" where porting programs requires recompilation and possibly source modification, and anything that requires non-POSIX Linux-specific features probably won't work.
