Question

File 1:

static char* const path; //GLOBAL

int main()
{
   path = FunctionReturningPath();
   UsePath()
}

File 2:

extern char* const path; //GLOBAL from file 1

UsePath() //function using global
{
   something = path;
}

(Pseudo)

Would like to use path in file 2.
I’m defining the global within main in file 1, is that bad practice using a global?

and doesn’t compile:

Compile Error: error LNK2001: unresolved external symbol _path

Any help is appreciated. Thank You.

Answer 1

static char* path; //GLOBAL

Wrong. making it static means it is local to the file, and cannot be exposed using extern. You want:

char* path; //GLOBAL
