Hi
What have I done wrong? Did createProcess close the handle, and is there a way round this?
The docs for runProcess says:
Any Handles passed to runProcess are placed immediately in the closed state.
but the equivalent seems to be missing from the documentation for createProcess.
However the createProcess command structure has the close_fds flag, which seems like it should override that behaviour, and therefore this seems like a bug in createProcess.
close_fds :: Bool Close all file descriptors except stdin, stdout and stderr in the new process This refers to inheriting open unix file descriptors (or Win32 HANDLEs) in the child process. It's not the same as closing the Haskell98 Handles in the parent process that you pass to the child process. Duncan
