ELF_STRPTR

NAME
elf_strptr - Return a pointer to a string in a string table section
SYNOPSIS
#include <libelf.h>
char *elf_strptr(Elf *elf, size_t section_index, size_t offset);
DESCRIPTION
The
elf_strptr()
function returns a pointer to a nul-terminated string located at
offset
bytes from the beginning of the string table section identified by
section_index.
The section must be of type
SHT_STRTAB.
This function validates the provided offset against the size of the string
table and ensures the string is nul-terminated. It transparently handles
both uncompressed and compressed sections.
If the ELF descriptor is not backed by memory mapping, or the section has
not been loaded yet, the function will read and initialize the necessary
data from the file.
PARAMETERS
- elf
-
Pointer to an ELF descriptor.
- section_index
-
The index of the string table section (of type
SHT_STRTAB).
- offset
-
The byte offset from the beginning of the string table section where
the desired string is located.
RETURN VALUE
Returns a pointer to the string within the string table if successful.
Returns
NULL
on error.
