Checks on the readiness of socket to perform operations.
The operations specified in condition are checked for and masked
against the currently-satisfied conditions on socket. The result
is returned.
Note that on Windows, it is possible for an operation to return
G_IO_ERROR_WOULD_BLOCK even immediately after
Socket.conditionCheck has claimed that the socket is ready for
writing. Rather than calling Socket.conditionCheck and then
writing to the socket if it succeeds, it is generally better to
simply try writing to the socket right away, and try again later if
the initial attempt returns G_IO_ERROR_WOULD_BLOCK.
It is meaningless to specify G_IO_ERR or G_IO_HUP in condition;
these conditions will always be set in the output if they are true.

This call never blocks.
