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

NAME
     gelf_getsyminfo, gelf_update_syminfo -- read and update symbol informa-
     tion

LIBRARY
     ELF Access	Library	(libelf, -lelf)

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-depen-
     dent 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 re-
     trieved or	updated.  The class-independent	GElf_Syminfo structure is de-
     scribed 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	argu-
     ment 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 suc-
     cessful, or NULL in case of an error.  Function gelf_update_syminfo() re-
     turns 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 num-
		       ber of symbols in the data descriptor.

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