52 // Synopsis: This function either logs a message to either stderr (if this
53 // is a checked build) or to the system log. It takes a variable
54 // number of arguments. Like printf, the first argument is a
55 // format string. Any subsequent parameters are replacements
56 // interpolated into the format string in place of variables.
58 // Arguments: char *szMessage - the format string (or whole message w/o subs)
59 // ... - subsequent arguments are interpolated into message.
