Description

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_open :: CFilePath -> CInt -> CMode -> IO CInt Source #

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

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.
