gSocketSend {RGtk2} | R Documentation

## gSocketSend

### 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

``object`` | a `GSocket`
``buffer`` | the buffer containing the data to send.
``size`` | the number of bytes to send
``cancellable`` | a `GCancellable` or `NULL`
`.errwarn` | Whether to issue a warning on error or fail silently

### 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. Since 2.22

### Value

A list containing the following elements:

`retval` | [integer] Number of bytes written (which may be less than `size`), or -1 on error
``error`` | `GError` for error reporting, or `NULL` to ignore.
