set_callsite_data(+SiteId, ?UserData)

   Associate arbitrary data with an instrumentation callsite 
   in a non-logical store.

Arguments
   SiteId              Integer
   UserData            Valid Prolog term

Type
   library(instrument)

Description

   Each code instrumentation point within a file is 
   uniquely identified by its callsite identifier.
   The callsite identifier is a monotonically increasing 
   integer incrementing from the initial value of 0 for a 
   new module. 
   
   The predicate associates arbitrary data (a valid Prolog term) 
   with a specified instrumentation callsite within a module or 
   file.
   
   The data is stored in a non-logical store and can be 
   retrieved using instrument:get_callsite_data/2.
   
   The predicate is a tool and data for a callsite 
   of a module other than the current calling module context 
   can be stored by invoking 
   set_callsite_data(SiteId, UserData)@Module.

Modules
   This predicate is sensitive to its module context (tool predicate, see @/2).

Fail Conditions
   no

Resatisfiable
   no

Exceptions
     4 --- SiteId is not instantiated.
     5 --- SiteId is not an integer.
