Method
GioSocketget_option
since: 2.36
Declaration [src]
gboolean
g_socket_get_option (
GSocket* socket,
gint level,
gint optname,
gint* value,
GError** error
)
Description [src]
Gets the value of an integer-valued option on socket, 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 #gint variable, not a #guchar;
g_socket_get_option() will handle the conversion internally.
Available since: 2.36
Parameters
level-
Type:
gintThe “API level” of the option (eg,

Type:
gint*Return location for the option value.
The argument will be set by 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 aNULLGError*.The argument will be left initialized to NULLby 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.
