System.Posix.Internals

POSIX support layer for the standard libraries. This library is built on *every* platform, including Win32.

Non-posix compliant in order to support the following features: * S_ISSOCK (no sockets in POSIX)

c_interruptible_open :: CFilePath -> CInt -> CMode -> IO CInt

The same as c_safe_open, but an interruptible operation as described in Control.Exception—it respects uninterruptibleMask but not mask.

We want to be able to interrupt an openFile call if it's expensive (NFS, FUSE, etc.), and we especially need to be able to interrupt a blocking open call. See #17912.
