The following flags can be used:
-
@b wxSOCKET_NONE
-
Normal functionality.
@b wxSOCKET_NOWAIT
-
Read/write as much data as possible and return immediately.
@b wxSOCKET_WAITALL
-
Wait for all required data to be read/written unless an error occurs.
@b wxSOCKET_BLOCK
-
Block the GUI (do not yield) while reading/writing data.
@b wxSOCKET_REUSEADDR
-
Allows the use of an in-use port (wxServerSocket only)
@b wxSOCKET_BROADCAST
-
Switches the socket to broadcast mode
@b wxSOCKET_NOBIND
-
Stops the socket from being bound to a specific adapter (normally used in
conjunction with @b wxSOCKET_BROADCAST)
A brief overview on how to use these flags follows.
-
If no flag is specified (this is the same as @b wxSOCKET_NONE),
IO calls will return after some data has been read or written, even
when the transfer might not be complete. This is the same as issuing
exactly one blocking low-level call to recv() or send(). Note
that @e blocking here refers to when the function returns, not
to whether the GUI blocks during this time.
-
If @b wxSOCKET_NOWAIT is specified, IO calls will return immediately.
Read operations will retrieve only available data. Write operations will
write as much data as possible, depending on how much space is available
low-level call to recv() or send(). Note that @e nonblocking here
refers to when the function returns, not to whether the GUI blocks during
this time.
-
If @b wxSOCKET_WAITALL is specified, IO calls won't return until ALL
the data has been read or written (or until an error occurs), blocking if
necessary, and issuing several low level calls if necessary. This is the
recv() or send() as needed so as to transfer all the data. Note
that @e blocking here refers to when the function returns, not
to whether the GUI blocks during this time.
-
The @b wxSOCKET_BLOCK flag controls whether the GUI blocks during
IO operations. If this flag is specified, the socket will not yield
during IO calls, so the GUI will remain blocked until the operation
completes. If it is not used, then the application must take extra
care to avoid unwanted reentrance.
-
The @b wxSOCKET_REUSEADDR flag controls the use of the SO_REUSEADDR standard
setsockopt() flag. This flag allows the socket to bind to a port that is
already in use.
use of wxSOCKET_REUSEADDR implies SO_REUSEPORT in addition to SO_REUSEADDR to
be consistent
with Windows.
-
The @b wxSOCKET_BROADCAST flag controls the use of the SO_BROADCAST standard
setsockopt() flag. This flag allows the socket to use the broadcast address,
and is generally
used in conjunction with @b wxSOCKET_NOBIND and wxIPaddress::BroadcastAddress.
-
So:
-
@b wxSOCKET_NONE will try to read at least SOME data, no matter how much.
-
@b wxSOCKET_NOWAIT will always return immediately, even if it cannot
read or write ANY data.
-
@b wxSOCKET_WAITALL will only return when it has read or written ALL
the data.
-
@b wxSOCKET_BLOCK has nothing to do with the previous flags and
it controls whether the GUI blocks.
-
@b wxSOCKET_REUSEADDR controls special platform-specific behavior for
reusing local addresses/ports.
