which (idb mode only)

Syntax

which name  

Parameters

Description

This command shows the full scope of an expression.

Use this command to determine to which declaration an identifier resolves. This command shows the fully qualified scope information for the instance of the specified expression visible from the current scope.

The scope information of a variable usually consists of the name of the source file that contains the function in which the variable is declared, the name of that function, and the name of the variable. The components of the scope information are separated by back-quotes ().

Example

The following example shows how to use the whereis and which commands to determine a variable's scope:
