elf_strptr(ELF)
elf_strptr --
make a string pointer
Synopsis
cc [flag . . . ] file . . . -lelf [library] . . .
#include <libelf.h>
char elf_strptr(Elf elf, size_t section, size_t offset);
Description
This function converts a string section
offset
to a string pointer.
elf
identifies the file in which the string section resides, and
section
gives the section table index for the strings.
elf_strptr
normally returns a pointer to a string, but it
returns a null pointer when
elf
is null,
section
is invalid or is not a section of type
SHT_STRTAB,
the section data cannot be obtained,
offset
is invalid, or an error occurs.
Examples
A prototype for retrieving section names appears below.
The file header specifies the section name string table
in the e_shstrndx
member.
The following code loops through the sections, printing
their names.
if ((ehdr = elf32_getehdr(elf)) == 0)
{
/ handle the error /
return;
}
ndx = ehdr->e_shstrndx;
scn = 0;
while ((scn = elf_nextscn(elf, scn)) != 0)
{
char name = 0;
if ((shdr = elf32_getshdr(scn)) != 0)
name = elf_strptr(elf, ndx, (size_t)shdr->sh_name);
printf("'%s'\n", name? name: "(null)");
}

Notices
A program may call
elf_getdata
to retrieve an entire string table section.
For some applications, that would be both
more efficient and more convenient than using
elf_strptr.
