NetBSD 6.1.5 - man page for gelf_update_syminfo (netbsd section 3)

GELF_GETSYMINFO(3)		   BSD Library Functions Manual 	       GELF_GETSYMINFO(3)

NAME
     gelf_getsyminfo, gelf_update_syminfo -- read and update symbol information

LIBRARY
     library ``libelf''

SYNOPSIS
     #include <gelf.h>

     GElf_Syminfo *
     gelf_getsyminfo(Elf_Data *data, int ndx, GElf_Syminfo *syminfo);

     int
     gelf_update_syminfo(Elf_Data *data, int ndx, GElf_Syminfo *syminfo);

DESCRIPTION
     These convenience functions are used to retrieve and update class-dependent Elf32_Syminfo
     and Elf64_Syminfo records in an ELF object.

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

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

     Function gelf_update_syminfo() converts the class-independent record pointed to by argument
     syminfo to class-dependent form, and writes it to the record at index ndx in the data buffer
     described by argument data.

RETURN VALUES
     Function gelf_getsyminfo() returns the value of argument syminfo if successful, or NULL in
     case of an error.	Function gelf_update_syminfo() 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 syminfo were NULL.

     [ELF_E_ARGUMENT]  Argument ndx was less than zero or larger than the number of symbols in
		       the data descriptor.

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