Detailed Description

Logging functions.

Logging functions are used to report some events that have happened in the system. These functions print messages to the standard error. It uses printf-like format strings.

A message is associated to a severity level. The severity level indicates the severity of the message and range from a simple debug message to a fatal message.

You can set the minimum severity for which messages are displayed. By default, the minimum severity level is gf::Log::Warning (or gf::Log::Debug if debug mode is activated at build time).

Example:

int entity = ...;
gf::Log::warning("Something weird happened to entity %i!\n", entity);
