# gelf\_update\_move(3)

Update class-independent move structure at the given index

## NAME

gelf\_update\_move - Update class-independent move structure at the given index

## SYNOPSIS

```
#include <gelf.h>
int gelf_update_move (Elf_Data *data, int ndx, GElf_Move *src);
```

## DESCRIPTION

This function copies a class-independent move structure from *src* into the **SHT\_SUNW\_move** section associated with *data* at entry index *ndx*.

*data* should be associated with an ELF section with type **SHT\_SUNW\_move** section. *data-\>d\_type* should be **ELF\_T\_MOVE**. These types are Sun/Solaris extensions and are not typically used in GNU/Linux ELF files.

## PARAMETERS

- *data*

  Pointer to an **Elf\_Data** associated with a **SHT\_SUNW\_move** section. *data-\>d\_type* should be **ELF\_T\_MOVE**.

- *ndx*

  Zero-based index of the move structure entry to be updated within *data*.

- *src*

  Pointer to a caller-provided move structure.  For **ELFCLASS32** binaries, **m\_info** and **m\_poffset** should be able to fit within unsigned 32-bit values. The **GELF\_M\_SIZE** component of **m\_info** should fit in unsigned 8 bits and the **GELF\_M\_SYM** component should fit in unsigned 24 bits. *src* must not be NULL.

## RETURN VALUE

On success, this function returns a non-zero value and updates the move entry at index *ndx* in *data*. The section associated with *data* is flagged with **ELF\_F\_DIRTY**. On failure, zero is returned and elf\_errno is set.  If *data* is NULL, then zero is returned without setting elf\_errno.
