Function Documentation

m_result_t m_module_create_module_dsr_list

(

struct list_head *

module_dsr_listp

)

Retrieve the list of loaded modules (e.g. libraries) that need to have their persistent data section mapped into this process.

Parameters:

module_dsr_listp

should point to the head of the list. This structure will be written with the list of modules which should be loaded in this address space.

void m_module_relocate_symbols	(	uintptr_t	got_start,
		uintptr_t	got_end,
		uintptr_t	old_start,
		uintptr_t	old_end,
		uintptr_t	new_start,
		uintptr_t	new_end
	)

Relocates symbols that fall in the range of addresses by offsetting their addresses stored in the global offset table (GOT).

Note: The actual data are not transferred. This function only hijacks the global offset table.
