obj The object file being relocated. rel The ELF relocation record. sect The section of the object file the relocation is for. symname The symbol's name. syminfo The ELF symbol info field. symvalue If a symbol is referenced, this is the symbols value.
- Return values
-
bool The relocation has been applied. bool The relocation could not be applied.
