DwarfCfiBuildFromElf

DwarfCfiBuildFromElf

Description

Parse the .eh_frame section of an already-opened ElfFile.

Parameters

Name Direction Description
out out Populated on success.
elf in ELF file to read from. Borrowed.
alloc in Allocator backing the CIE / FDE vectors.

Success

Returns true. out->fdes.length may be 0 if the binary lacks a .eh_frame section (very unusual on modern Linux).

Failure

Returns false; logs the failing step. out is left zeroed.
