call_with_unix_fd_list
Description:
[ Version ( since = "2.30" ) ]
public async Variant call_with_unix_fd_list (string? bus_name, string object_path, string interface_name, string method_name, Variant? parameters, VariantType? reply_type, DBusCallFlags flags, int timeout_msec, UnixFDList? fd_list = null, Cancellable? cancellable = null, out UnixFDList? out_fd_list = null) throws Error
Like call but also takes a UnixFDList object.
The file descriptors normally correspond to g_variant_type_handle values in the body of the message. For
example, if a message contains two file descriptors, fd_list would have length 2, and `g_variant_new_handle (0)` and
`g_variant_new_handle (1)` would appear somewhere in the body of the message (not necessarily in that order!) to represent the file descriptors
at indexes 0 and 1 respectively.
When designing D-Bus APIs that are intended to be interoperable, please note that non-GDBus implementations of D-Bus can usually only access file descriptors if they are referenced in this way by a value of type g_variant_type_handle in the body of the message.
This method is only available on UNIX.
Parameters:
