NAME

elf32_checksum, elf64_checksum - compute the checksum for a 32-bit or 64-bit ELF object file

SYNOPSIS

#include <libelf.h>

long int elf32_checksum(Elf * elf );
long int elf64_checksum(Elf *
elf );

DESCRIPTION

Compute a checksum for the ELF object file referred to by elf . The checksum is computed from permanent parts of the ELF file and the result is repeatable. To be repeatable, strippable sections are not included in computing the checksum. SHT_NOBITS sections are also not included when computing the checksum. The checksum can be used as a value for DT_CHECKSUM .

PARAMETERS

elf

The ELF object file for which the checksum is to be computed.

RETURN VALUE

On success, return the computed checksum. If an error occurs, return -1 and set a libelf error code. The checksum is always calculated as a 4-byte value. If long int is larger than 4 bytes, then the checksum will be extended by padding with zeros.

SEE ALSO

elf_errno (3), libelf (3), elf (5)

ATTRIBUTES

For an explanation of the terms used in this section, see attributes (7).
