Detailed Description

Package to load : lib/std/error.pkg

This API provides an high level method to easily include a customized error manager

You can :

define your masks yourself
enabled / disabled this manager
define your code numbers and messages error
write - or not - in the Scol console
use a hard file log or a temporary file log
and more things yet

It is NOT recommanded to use the internal STD_ERROR structure to any application. Use this API instead.

To use it with the Console library (lib/console), this API requires too the lib/console/console.pkg package.

Prototype: fun [STD_ERROR CONSOLE I I] I

Parameters

STD_ERROR	: a manager object
CONSOLE	: an EasyConsole object
I	: a predefined number error
I	: a mask for this message. It is tested with the mask of the manager to determine wether the message should be written. If the test is positive, the message is immediatly written. Thus, the logical 'mask_of_manager & mask_of_this_message' must be at not null to write the message.
