=category Logging
This is the main entry point to logging. Note that the extra set of
parentheses are required due to limitations in C89 macros.
This will format a string with the current file and line number to the
log file if logging is enabled.
This must be called with a context object defined by one of the
C<dIMCTX> macros in scope.
This can also be called as C<mm_log((level, format, args))> in which
case the currently active context is used and any in scope context is
ignored.
