The logging functionality uses a "channel" design, so you can enable and
disable feature-specific logging at runtime. The macros of interest are:

GINFOC( ) - Log to a specific channel, eg:
GINFOC( 'v', "Video blah blah" );

GINFO( ) - Log to the channel set in GINFOCHANNEL (at the top of the file)
#undef GINFOCHANNEL
#define GINFOCHANNEL 'v'
...
GINFO( "Video blah blah" );

GWARN( ) - Log a warning; not tied to any channel (always logged)

As for the functions, the only one that really matters is:

GLogFilterSet( ) - Changes which channels are enabled, eg:
GLogFilterSet( "vrV" );

There are 52 channels: each uppercase and lowercase letter is its own
channel. Furthermore, enabling the channel 'x' enables all lower-cased
channels, and 'X' enables all uppercase.

Does this answer your question?
