[Xcb] [xsync] attributes of XCBSyncCreateAlarm

[Vincent Torri]

Hey,

a question about that function again.

I suppose that I have defined the flags for the attributes of 
XCBSyncCreateAlarm. Now I need to set the values of value_list, which is a 
pointer on a CARD32.

I suppose that I want to set the value of all the 6 attributes. My 
question is :

should value_list be of type

CARD32 value_list[6]
because there are 6 values,

or of type a pointer on the following structure:

struct {
   XCBSyncTRIGGER trigger;
   XCBSyncINT64   delta;
   BOOL           events;
}
and after that, I cast to a pointer on CARD32

?

thank you

Vincent

C enums don't actually specify a physical size, so these might be incorrect compared to the wire protocol (xextproto/syncstr.h).
