long elf32_checksum(Elf *elf);
long elf64_checksum(Elf *elf);
The elf32_checksum() function returns a simple checksum of selected
sections of the image identified by elf. The value is typically used as
the .dynamic tag DT_CHECKSUM, recorded in dynamic executables
and shared objects.
Selected sections of the image are used to calculate the checksum
in order that its value is not affected by utilities such as
strip(1).
For the 64−bit class, replace 32 with 64 as
appropriate.
