# gelf\_getlib(3)

Get prelink library from table at the given index

## NAME

gelf\_getlib - Get prelink library from table at the given index

## SYNOPSIS

```
#include <gelf.h>
GElf_Lib *gelf_getlib (Elf_Data *data, int ndx, GElf_Lib *dst);
```

## DESCRIPTION

Retrieve a prelink library table entry from *data* at index *ndx* and store it in the class-independent representation pointed to by *dst*.

*data* must be an **Elf\_Data\*** associated with a section of type **SHT\_GNU\_LIBLIST**. *data-\>d\_type* should be **ELF\_T\_LIB**. **SHT\_GNU\_LIBLIST** sections are used by the prelink utility.  See https://sourceware.org/gnu-gabi/prelink.txt for more information.

## PARAMETERS

- *data*

  Pointer to an **Elf\_Data** of a section with type **SHT\_GNU\_LIBLIST**. *data-\>d\_type* should be **ELF\_T\_LIB**.

- *ndx*

  Zero-based index of the requested prelink library table entry within *data*.

- *dst*

  Pointer to a caller-provided **GElf\_Lib** structure for storing the requested prelink library table entry. Must not be NULL.

## RETURN VALUE

On success, this function updates *dst* with the requested prelink library table entry and returns *dst*. On failure, it returns NULL and sets elf\_errno.  If *data* is NULL, then NULL is returned without setting elf\_errno.
