Functions elf32_getehdr() and elf64_getehdr() return a pointer to the appropriate class-specific header descriptor if it exists in the file referenced by descriptor elf. These functions return NULL if an ELF header was not found in file elf.
Function gelf_getehdr() stores a translated copy of the header for ELF file elf into the descriptor pointed to by argument dst. It returns argument dst if successful or NULL in case of failure.
