16 | /* An external symbol is something not defined by the module | |
17 | * (executable or library) being built. Rather, it is provided | |
18 | * from a library dependency (dll, dylib, or shared object). | |
19 | * | |
20 | * A public symbol is defined in this module as being available | |
21 | * to users outside of this module. If building a library, this | |
22 | * means the symbol will be part of the public interface. | |
23 | * | |
24 | * A private symbol is defined within this module, but will not | |
25 | * be made available outside of it. This is typically used for | |
26 | * internal implementation details that should not be accessible. | |
