get_option


Description:

[ Version ( since = "2.36" ) ]
public bool get_option (int level, int optname, out int value) throws Error

Gets the value of an integer-valued option on this, as with getsockopt.

(If you need to fetch a non-integer-valued option, you will need to call getsockopt directly.)

The <gio/gnetworking.h> header pulls in system headers that will define most of the standard/portable socket options. For unusual socket protocols or platform-dependent options, you may need to include additional headers.

Note that even for socket options that are a single byte in size, value is still a pointer to a int variable, not a uchar; get_option will handle the conversion internally.

Parameters:

this

a Socket

level

the "API level" of the option (eg, `SOL_SOCKET`)

optname

the "name" of the option (eg, `SO_BROADCAST`)

value

return location for the option value

Returns:

success or failure. On failure, throws will be set, and the system error value (`errno` or WSAGetLastError) will still be set to the result of the getsockopt call.
