*
* Internal header for ICU tracing / logging .
*
*
* Various notes :
* - using a trace level variable to only call trace functions
* when the level is sufficient
* - using the same variable for tracing on / off to never make a function
* call when off
* - the function number is put into a local variable by the entry macro
* and used implicitly to avoid copy & paste / typing mistakes by the developer
* - the application must call utrace_setFunctions ( ) and pass in
* implementations for the trace functions
* - ICU trace macros call ICU functions that route through the function
* pointers if they have been set ;
* this avoids an indirection at the call site
* ( which would cost more code for another check and for the indirection )
*
* # # # TODO Issues :
* - Verify that va_list is portable among compilers for the same platform .
* va_list should be portable because printf ( ) would fail otherwise !
* - Should enum values like UTraceLevel be passed into int32_t - type arguments ,
* or should enum types be used ?
