| Description |
| A module containing semi-public Network.Socket internals.
Modules which extend the Network.Socket module will need to use
this module while ideally most users will be able to make do with
the public interface.

| Read a SockAddr from the given memory location.
|
|
|
| Write the given SockAddr to the given memory location.
|
|
|
| Computes the storage requirements (in bytes) of the given
SockAddr. This function differs from sizeOf
in that the value of the argument is used.
|
|
|
| Computes the storage requirements (in bytes) required for a
SockAddr with the given Family.
|
|
|
| Use a SockAddr with a function requiring a pointer to a
SockAddr and the length of that SockAddr.
|
|
|
| Create a new SockAddr for use with a function requiring a
pointer to a SockAddr and the length of that SockAddr.

| Socket error functions
|
|
|
| :: | | | => String | textual description of the error location
| | -> IO a | | | Throw an IOError corresponding to the current socket error.
|
|
|
| Guards for socket operations that may fail
|
|
| throwSocketErrorIfMinus1_ | Source |
|
| :: Num a | | | => String | textual description of the location
| | -> IO a | the IO operation to be executed
| | -> IO () | | | Throw an IOError corresponding to the current socket error if
the IO action returns a result of -1. Discards the result of the
IO action after error handling.
|
|
|
| throwSocketErrorIfMinus1Retry | Source |
|
| :: Num a | | | => String | textual description of the location
| | -> IO a | the IO operation to be executed
| | -> IO a | | | Throw an IOError corresponding to the current socket error if
the IO action returns a result of -1, but retries in case of an
interrupted operation.
|
|
|
| throwSocketErrorIfMinus1RetryMayBlock | Source |
|
| :: Num a | | | => String | textual description of the location
| | -> IO b | action to execute before retrying if an
immediate retry would block
| | -> IO a | the IO operation to be executed
| | -> IO a | | | Throw an IOError corresponding to the current socket error if
the IO action returns a result of -1, but retries in case of an
interrupted operation. Checks for operations that would block and
executes an alternative action before retrying in that case.
|
|
|
| Initialization
|
|
|
On Windows operating systems, the networking subsystem has to be
initialised using withSocketsDo before any networking operations can
be used. eg.
main = withSocketsDo $ do {...}
Although this is only strictly necessary on Windows platforms, it is
harmless on other platforms, so for portability it is good practice to
use it all the time.
