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-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
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 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()
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 num‐
ber of symbols in the data descriptor.
[ELF_E_ARGUMENT] Data descriptor data was not associated with a section
containing symbol information.
