NAME
gelf_getsym - Retrieve class-independent symbol information from the symbol
table at the given index
SYNOPSIS
#include <gelf.h>
GElf_Sym *gelf_getsym (Elf_Data *data, int ndx, GElf_Sym *dst);
DESCRIPTION
Translate the symbol table entry at index
ndx
from
data
into a class-independent representation stored in
*dst.
data
must be the
Elf_Data
of a section with type
SHT_SYMTAB
or
SHT_DYNSYM.
The number of symbols in the symbol table can be calculated by dividing the
size of the corresponding section (sh_size or d_size)
by the size of a symbol table entry. The size of a symbol table entry can be
obtained from
sh_entsize
or
gelf_fsize(3).
If the corresponding elf contains more than 64K sections then
gelf_getsymshndx
should be used to retrieve a symbol's section index. See
gelf_getsymshndx(3)
for more information.
PARAMETERS
- data
-
Pointer to an
Elf_Data
of a
SHT_SYMTAB
or
SHT_DYNSYM
section.
- ndx
-
Zero-based index of the symbol table entry within
data.
- dst
-
Pointer to a caller-provided structure for storing the symbol table entry.
dst
must not be NULL.
RETURN VALUE
On success, this function returns
dst.
On failure, it returns NULL and sets elf_errno. If
data
is NULL, then NULL is returned without setting elf_errno.
