Function __LINE__

 		Previous pageReturn to chapter overviewNext page   

Returns line number of the current code.

 

Unit

EDebugInfo

 

Syntax

 

Code (Delphi)

function __LINE__: Integer;

 

Return value

Line number for the caller. For example: 42.

 

Remarks

This function is a simple combination of GetLocationInfo and GetCaller functions.

 

Note

Please note that line number belongs to source code, not the unit. While these are the same most of the time, it is not always so. For example, if you add an include file with code, then unit name will be something like 'Unit1', while line numbers will be from Code.inc for all code inside the include file. The same is true for generics. Unit name may be 'Unit1.pas', while line numbers will be taken from System.Generics.Collections.pas.
