Qt-Generic-TypedefCheck

Do not redefine a typedef

Required inputs: IR

This rule will warn when there are multiple definitions for a typedef. Usually, each typedef should be defined only a single time in a header file.

Note that if multiple definitions of a typedef exist, all those definitions must be equivalent to avoid violating the One Definition Rule (which causes undefined behavior).

Possible Messages

Key	Text	Severity	Disabled
differing_typedef_redefinition	Typedef redefined with different definition.	None	False
identical_typedef_redefinition	Typedef redefined.	advisory	False
