- return checksum of elf image
cc [ flag ... ] file ... -lelf [ library ... ] #include <libelf.h> 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 calcluate 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.
