@hackage select0.4

While tinkering on a project, I frequently found myself having to make FFI calls to select(2). This package provides an interface to that system call.

Changes in version 0.4:

• Introduce an interface to fd_set.

• Add functions with various amounts of abstraction; in particular, select'' matches select in previous versions.

• Retry select(2) in case of interruption by signals.

• Remove dependence on the vector package.

WARNINGS:

• Behavior with write and exception file descriptors is under-tested. Feedback is welcome.

• This package is far from complete, and should be tested throughly before being relied upon.

TODO:

• Return the error code specified by errno if select fails.

• Possibly move the select retry code from C to Haskell.

• Reorder functions to make the documentation more logical.

• Use hsc2hs's #const to get preprocessor constants (removes some of FdSet's cbits.c).

NOTE: I feel I'm occupying prime namespace realestate with a package name like select. I'll happily let myself be chased away if someone more qualified wants to use this package name. Let me know.
