Description
Tries to send size bytes from buffer on the socket. This is
mainly used by connection-oriented sockets; it is identical to
gSocketSendTo with address set to NULL.Usage
gSocketSend(object, buffer, size, cancellable = NULL, .errwarn = TRUE)
Arguments
buffer
the buffer containing the data to send.
size
the number of bytes to send
.errwarn
Whether to issue a warning on error or fail silently
Value
A list containing the following elements:
- retval
- [integer] Number of bytes written (which may be less than
size), or -1
on error errorGError for error reporting, or NULL to ignore.
Details
If the socket is in blocking mode the call will block until there is
space for the data in the socket queue. If there is no space available
and the socket is in non-blocking mode a G_IO_ERROR_WOULD_BLOCK error
will be returned. To be notified when space is available, wait for the
G_IO_OUT condition. Note though that you may still receive
G_IO_ERROR_WOULD_BLOCK from gSocketSend even if you were previously
notified of a G_IO_OUT condition. (On Windows in particular, this is
very common due to the way the underlying APIs work.)
On error -1 is returned and error is set accordingly.
