I presume there's no typedef for it then. Instead try:
[CCode (lower_case_cprefix = "", has_target = false)]
public delegate void ConnectPort(Handle? instance, ulong
port, ref double dataLocation);
The lower_case_cprefix should remove the default namespace prefix
and then ConnectPort will be converted to connect_port in C.
That's my interpretation of the last paragraph of:
https://wiki.gnome.org/Projects/Vala/LegacyBindings#Delegates
If that doesn't work, I'm not sure what else to suggest. The paragraph could
mean include an empty cname, e.g.
[CCode (cname = "", has_target = false)]
public delegate void DescriptorConnectPort(Handle? instance, ulong
port, ref double dataLocation);
Use the --ccode switch with valac to get the C code produced. Look at the
code and tweak it until it works then work back to the VAPI. You can use
valac to compile C. Just use valac --pkg xyz my_c_file.c
