Module `Eio_unix.FD`Source

Convert between Unix.file_descr and Eio objects.

Sourceval peek : < unix_fd.. > -> Unix.file_descr

peek x is the Unix file descriptor underlying x. The caller must ensure that they do not continue to use the result after x is closed.

Sourceval peek_opt : Eio.Generic.t -> Unix.file_descr option

peek_opt x is the Unix file descriptor underlying x, if any. The caller must ensure that they do not continue to use the result after x is closed.

Sourceval take : < unix_fd.. > -> Unix.file_descr

take x is like peek, but also marks x as closed on success (without actually closing the FD). x can no longer be used after this, and the caller is responsible for closing the FD.

Sourceval take_opt : Eio.Generic.t -> Unix.file_descr option

take_opt x is like peek_opt, but also marks x as closed on success (without actually closing the FD). x can no longer be used after this, and the caller is responsible for closing the FD.

val as_socket : 
  sw:Eio.Std.Switch.t ->
  close_unix:bool ->
  Unix.file_descr ->
  socket

as_socket ~sw ~close_unix:true fd is an Eio flow that uses fd. It can be cast to e.g. Eio.source for a one-way flow. The socket object will be closed when sw finishes.

parameter close_unix
If true, closing the object will also close the underlying FD. If false, the caller is responsible for keeping FD open until the object is closed.
