GELF_GETMOVE(3)		 BSD Library Functions Manual	       GELF_GETMOVE(3)

NAME
     gelf_getmove, gelf_update_move — read and update Elf Move information

LIBRARY
     library “libelf”

SYNOPSIS
     #include <gelf.h>

     GElf_Move *
     gelf_getmove(Elf_Data *data, int ndx, GElf_Move *move);

     int
     gelf_update_move(Elf_Data *data, int ndx, GElf_Move *move);

DESCRIPTION
     These convenience functions are used to retrieve and update class-depen‐
     dent Elf32_Move and Elf64_Move structures in an ELF object.

     Argument data is an Elf_Data descriptor associated with a section of type
     SHT_SUNW_move.  Argument ndx is the index of the move record being
     retrieved or updated.  The class-independent GElf_Move structure is
     described in gelf(3).

     Function gelf_getmove() retrieves class-dependent move record at index
     ndx in data buffer data and copies it to the destination pointed to by
     argument move after translation to class-independent form.

     Function gelf_update_move() converts the class-independent move informa‐
     tion pointed to by argument move to class-dependent form, and writes it
     to the move record at index ndx in the data buffer described by argument
     data.  Function gelf_update_move() signals an error if any of the values
     in the class-independent representation exceeds the representable limits
     of the target type.

RETURN VALUES
     Function gelf_getmove() returns the value of argument move if successful,
     or NULL in case of an error.  Function gelf_update_move() returns a non-
     zero value if successful, or zero in case of an error.

ERRORS
     These functions may fail with the following errors:

     [ELF_E_ARGUMENT]  Arguments data or move were NULL.

     [ELF_E_ARGUMENT]  Argument ndx was less than zero or larger than the num‐
		       ber of records in the data descriptor.

     [ELF_E_ARGUMENT]  Data descriptor data was not associated with a section
		       containing move information.

     [ELF_E_RANGE]     A value was not representable in the target type.
