Function Documentation

get_eh_frame_list()

struct eh_frame_t* get_eh_frame_list ( )

noexcept

Get EH Framework List

Precondition

expects: none

Postcondition

ensures: ret != nullptr

Returns a list of ".eh_frame" sections, containing their start address, and size. This is used by the unwind library to find stack frames. The list should have one .eh_frame section for each module that is loaded.

Returns

eh_frame list (of size MAX_NUM_MODULES)

Definition at line 39 of file misc_all.cpp.

register_eh_frame()

int64_t register_eh_frame ( void *  addr, uint64_t  size  )

noexcept

Register EH Framework

Registers an ".eh_frame" section, containing it's start address, and size. This will add the eh_frame section to a global list that can be retreived using get_eh_frame_list

Precondition

expects: addr != nullptr

expects: size != 0

Postcondition

ensures: none

Parameters

addr	the address of the eh_frame section
size	the size of the eh_frame section

Returns

REGISTER_EH_FRAME_SUCCESS on success, REGISTER_EH_FRAME_FAILURE on failure
