[Xcb] [xsync] attributes of XCBSyncCreateAlarm

[Vincent Torri]

Hello,

Usually, for a list of attributes, there is an enum defined in the header 
file of the extension. I don't see any in the sync.h file.

According to the doc of the sync protocol, the attributes of 
XCBSyncCreateAlarm are:

trigger: of type TRIGGER (counter, value-type, value, test-type)
delta  : of type int64
events : of type bool

so, how can i use attributes with XCBSyncCreateAlarm ?

thank you

Vincent
