[PATCH 12/15] submodule-config: move submodule-config functions to submodule-config.c

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Migrate the functions used to initialize the submodule-config to
submodule-config.c so that the callback routine used in the
initialization process can be static and prevent it from being used
outside of initializing the submodule-config through the main API.
