Hi all,
Got a problem with variadic arguments.
I have a function thus:
void XVLogEvent( NSString* format, ... )
{
NSString* logString;
va_list argsP;
va_start( argsP, format );
logString = [NSString stringWithFormat:format, argsP];
va_end(argsP);
XVEventLog* logger = [XVEventLog sharedEventLog];
[logger appendLog:logString];
}
This function is invoked by a macro so I can easily deploy a special type of
logging. The problem I have is with the line:
logString = [NSString stringWithFormat:format, argsP];
which causes an EXC_BAD_ACCESS. Obviously I’m doing it wrong, but if I use
NSLogv here, it works fine. How do I turn my variadic parameters into a fully
formatted string?
