elf64_getehdr - retrieve the ELF header for a 64-bit ELF descriptor

elf64_getehdr retrieves the ELF header for the given 64-bit ELF descriptor elf. The ELF header contains crucial metadata about the ELF file, such as the type, machine, version, entry point, program header table offset, and section header table offset. See elf(5) for more information regarding the ELF header.
