GELF_GETCLASS(3) BSD Library Functions Manual GELF_GETCLASS(3)NAME
gelf_getclass -- retrieve the class of an ELF descriptor
ELF Access Library (libelf, -lelf)
Function gelf_getclass() returns the ELF class of the descriptor supplied in argument elf.
Function gelf_getclass() will return one of ELFCLASS32 or ELFCLASS64 if the argument elf is a descriptor for an ELF file. The value
ELFCLASSNONE is returned if argument elf was null, or if it was not a descriptor for an ELF file.

GELF_CHECKSUM(3) BSD Library Functions Manual GELF_CHECKSUM(3)NAME
elf32_checksum, elf64_checksum, gelf_checksum -- return the checksum of an ELF object
ELF Access Library (libelf, -lelf)
These functions return a simple checksum of the ELF object described by their argument elf. The checksum is computed in way that allows its
value to remain unchanged in presence of modifications to the ELF object by utilities like strip(1).
Function elf32_checksum() returns a checksum for an ELF descriptor elf of class ELFCLASS32.
Function elf64_checksum() returns a checksum for an ELF descriptor elf of class ELFCLASS64.
Function gelf_checksum() provides a class-independent way retrieving the checksum for ELF object elf.
These functions return the checksum of the ELF object, or zero in case an error was encountered.
These functions may fail with the following errors:
[ELF_E_ARGUMENT] Argument elf was NULL.
[ELF_E_ARGUMENT] Argument elf was not a descriptor for an ELF file.
[ELF_E_ARGUMENT] The ELF descriptor elf was not opened for reading or updating.
[ELF_E_CLASS] For functions elf32_checksum() and elf64_checksum(), ELF descriptor elf did not match the class of the called function.
[ELF_E_HEADER] The ELF object specified by argument elf had a malformed executable header.
[ELF_E_RESOURCE] An out of memory condition was detected during processing.
[ELF_E_SECTION] The ELF object specified by argument elf contained a section with a malformed section header.
[ELF_E_VERSION] The ELF object was of an unsupported version.

I installed NetBSD 6.1.2 amd64 and can't find the apm utility. Is it not in the base system?
Is it necessary to recompile the default amd64 kernel to use apm?
Or is there a new method for power management and suspend/resume? (2 Replies)
