Calling Global Constructors: Difference between revisions

It is very simple to implement this under x86. You simply have to define the header of two functions in crti.o and the footer in crtn.o and use these objects in your C library or kernel. You can then simply call _init to perform the initialization tasks and call _fini to perform the termination tasks (normally done from a crt0.o or my-kernel-boot-object.o).
