\brief Generic ELF library
|
||||
|
||||
The ELF library is designed to make the task of parsing and getting information
|
||||
out of an ELF file easier.
|
||||
|
||||
It provides function to obtain the various different fields in the ELF header, and
|
||||
the program and segment information.
|
||||
|
||||
Also importantly, it provides a function elf_loadFile which will load a given
|
||||
ELF file into memory.
