ELF (Executable and Linking Format).

elf文档
There are three main types of object files.
• A relocatable file holds code and data suitable for linking with other object files to create an
executable or a shared object file.
• An executable file holds a program suitable for execution.
• A shared object file holds code and data suitable for linking in two contexts. First, the link
editor may process it with other relocatable and shared object files to create another object file.
Second, the dynamic linker combines it with an executable file and other shared objects to
create a process image.
