Extern enum




extern enum myenum enum_var; data.c: enum myenum enum_var; The "extern" means it's a declaration but not a definition; it doesn't create the variable, it merely declares that it exists elsewhere. This all assumes that you really want a global variable. Perhaps you do, but it's very likely that you don't.--

I created an enum in a file as follows: Code: enum { SOME_VAL=201, 2020-11-16 · the extern keyword is used to extend the visibility of variables/functions. Since functions are visible throughout the program by default, the use of extern is not needed in function declarations or definitions.

Extern is a way to use global variable in multiple files. Simple approach of extern is: Declare extern varaible: This should be done in header file. For ex: in STATE_Declaration.h: typedef enum{ STATE_HOME, STATE_SETUP, } STATE; extern STATE state; /*Extern Declaration (NOTE:enum is not needed )*/

This is the job header files were born to do. You can put the enum definition and the extern in the header, and any source code that needs to know about it #includes the header. 06-22-2011 #3 An enum is a data type, not a variable. The compiler needs to know the definition of the enum before you can use it, or you'll get an "unknown struct/union/enum" error. You need to define the full enum in a header file.
