Detailed Description

ELF program header.

An executable or shared object file's program header table is an array of structures, each describing a segment or other information the system needs to prepare the program for execution. An object file segment contains one or more sections. Program headers are meaningful only for executable and shared object files. A file specifies its own program header size with the ELF header's Elf32_Ehdr::e_phentsize and Elf32_Ehdr::e_phnum members.
