Options

• This rule shares the following common options: exclude_in_macros, exclude_messages_in_system_headers, excludes, extend_exclude_to_macro_invocations, includes, justification_checker, languages, post_processing, provider, report_at, severity

• The following places define options that affect this rule: Stylechecks, Analysis-GlobalOptions

accept_const_fields

accept_const_fields : bool = False

Whether const-qualified static fields in header files should be tolerated if they have internal linkage. Has no effect on violations about external definitions.

 

accept_const_variables

accept_const_variables : bool = True

Whether global const-qualified variables in header files should be tolerated if they have internal linkage. Has no effect on violations about external definitions.

 

find_non_external_function_declaration

find_non_external_function_declaration : bool = True

Whether function declarations with non-external linkage should be reported.

 

report_tentative_definitions

report_tentative_definitions : bool = False

Whether tentative definitions should be reported as well.
