LOGMINLEVEL

The _LOGMINLEVEL function returns the current minimum logging level that is being output.

Syntax

level& = _LOGMINLEVEL

Parameters

• The return value level& is a number from 1 to 5 indicating the current minimum level of logging enabled. The below table indicates the mapping:

┌────────┬─────────────┐ │ Number │ Log level │ ├────────┼─────────────┤ │ 1 │ Trace │ ├────────┼─────────────┤ │ 2 │ Information │ ├────────┼─────────────┤ │ 3 │ Warning │ ├────────┼─────────────┤ │ 4 │ Error │ ├────────┼─────────────┤ │ 5 │ None │ └────────┴─────────────┘ Description * The purpose of _LOGMINLEVEL is to allow programs to skip generating expensive logging if that logging would not be output anywhere. * For example, you may have a very large array of integers that you want to log fairly often - generating the strings of the log messages for that array can slow down your program even if those messages are ultimately never written anywhere. By checking _LOGMINLEVEL before generating those log messages you can avoid that expensive work if it would not be used but also still produce it when you request it. * If the function returns a 2, that indicates that only logging at the Information level and above is being captured somewhere. If the function returns a 5, that means no logging is being captured anywhere.
