problems with VC98\INCLUDE

[aidanh]

I have been given a bit of source code which I am trying
to compile!

The code uses the functions

SetupDiGetClassDevs( ... )
SetupDiEnumDeviceInterfaces( ... )

which are in setupapi.lib

Unfortunately I get the error messages

error C2664: 'SetupDiGetClassDevsA' : cannot convert
parameter 1 from 'const struct _GUID *' to 'struct _GUID *'


looking at my .h files I see that param 1 takes a 'struct
_GUID' but in the msdn site it takes 'const struct _GUID'

I am led to believe my sdk is out of date!!

does anyone know where I can find the updates, I have
looked everywhere

I have already installed SP5

thank everyone and have a goog christmas

put (struct _GUID *)yourGuid instead of just yourGuid

1. I looks like you have a constant struct
2. You are not passing it as a pointer, use an & before your struct

The star above marked with red means in the code is a kind of pointer to GUID. The green one means compiller wants another kind of pointer to GUID. There is quite enough a pointer conversion.
