Method

GioSocketreceive_bytes

since: 2.80

Declaration 

GBytes*
g_socket_receive_bytes (
  GSocket* socket,
  gsize size,
  gint64 timeout_us,
  GCancellable* cancellable,
  GError** error
)

Description

Receives data (up to size bytes) from a socket.

This function is a variant of g_socket_receive() which returns a GBytes rather than a plain buffer.

Pass -1 to timeout_us to block indefinitely until data is received (or the connection is closed, or there is an error). Pass 0 to use the default timeout from GSocket:timeout, or pass a positive number to wait for that many microseconds for data before returning G_IO_ERROR_TIMED_OUT.

Available since: 2.80

Parameters

size

Type: gsize

The number of bytes you want to read from the socket.

timeout_us

Type: gint64

The timeout to wait for, in microseconds, or -1 to block indefinitely.

cancellable

Type: GCancellable

A %GCancellable, or NULL

The argument can be NULL.
The data is owned by the caller of the function.
error

Type: GError **

The return location for a recoverable error.

The argument can be NULL.
If the return location is not NULL, then you must initialize it to a NULL GError*.
The argument will left initialized to NULL by the method if there are no errors.
In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.

Return value

Type: GBytes

A bytes buffer containing the received bytes, or NULL on error.

The caller of the method takes ownership of the data, and is responsible for freeing it.
