Duplicate enumeration member names

Specify the action to take if the code generator detects two enumeration types with same member names

Model Configuration Pane: Code Generation / Identifiers

Description

Select the diagnostic action to take if the code generator detects two enumeration types with same member names. This parameter applies to only enumeration with imported data scope and the same storage type and value.

Settings

error (default) | none | warning

none: When the code generator detects two enumeration types with the same member names, the code generation proceeds.
warning: When the code generator detects two enumeration types with the same member names, the software issues a warning message and the code generation proceeds.
error: When the code generator detects two enumeration types with the same member names, the software issues an error message and terminates the code generation.

Handle Duplicate Enumeration Member Names

Consider these enumerations:

typedef int32_T enumA;
#define a       (0)
#define p       (1)

typedef int32_T enumB;
#define b       (0)
#define p       (1)

The enumerations have the same int32 storage type. The enumeration member p with value 1 is the same for enumA and enumB.

Generate an error or warning message or allow code generation for duplicate enumeration member names by using the Duplicate enumeration member names configuration parameter.
