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
Vt Elf32_Syminfo
and
Vt Elf64_Syminfo
records in an ELF object.
Argument
data
is an
Vt 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
Vt 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:
Bq Er ELF_E_ARGUMENT
Arguments
data
or
syminfo
were NULL.
Bq Er ELF_E_ARGUMENT
Argument
ndx
was less than zero or larger than the number of symbols in the data
descriptor.
Bq Er ELF_E_ARGUMENT
Data descriptor
data
