GELF_FSIZE(3)						   BSD Library Functions Manual 					     GELF_FSIZE(3)

NAME

     gelf_fsize, elf32_fsize, elf64_fsize -- return the size of a file type

LIBRARY

     ELF Access Library (libelf, -lelf)

SYNOPSIS

     #include <libelf.h>

     size_t
     elf32_fsize(Elf_Type type, size_t count, unsigned int version);

     size_t
     elf64_fsize(Elf_Type type, size_t count, unsigned int version);

     #include <gelf.h>

     size_t
     gelf_fsize(Elf *elf, Elf_Type type, size_t count, unsigned int version);

DESCRIPTION

     These functions return the size in bytes of the file representation of count numbers of objects of ELF type type.

     Functions elf32_fsize() and elf64_fsize() return sizes for files of class ELFCLASS32 and ELFCLASS64 respectively.	Function gelf_fsize()
     returns the size for the class of ELF descriptor elf.

RETURN VALUES

     These functions return a non-zero value in case of success, or zero in case of an error.

ERRORS

     These functions may fail with:

     [ELF_E_ARGUMENT]  Argument elf was NULL in a call to gelf_fsize().

     [ELF_E_ARGUMENT]  ELF descriptor elf had an unknown ELF class.

     [ELF_E_ARGUMENT]  Argument type contained an illegal value.

     [ELF_E_UNIMPL]    Support for ELF type type has not been implemented.

     [ELF_E_VERSION]   Argument version is not a supported version.

GELF_CHECKSUM(3)					   BSD Library Functions Manual 					  GELF_CHECKSUM(3)

NAME

     elf32_checksum, elf64_checksum, gelf_checksum -- return the checksum of an ELF object

LIBRARY

     ELF Access Library (libelf, -lelf)

SYNOPSIS

     #include <libelf.h>

     long
     elf32_checksum(Elf *elf);

     long
     elf64_checksum(Elf *elf);

     #include <gelf.h>

     long
     gelf_checksum(Elf *elf);

DESCRIPTION

     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.

RETURN VALUES

     These functions return the checksum of the ELF object, or zero in case an error was encountered.

ERRORS

     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.
