# elf\_version(3)

set the ELF version for libelf.

## NAME

elf\_version - set the ELF version for libelf.

## SYNOPSIS

**#include \<libelf.h\>**

**unsigned int elf\_version(unsigned int** *version***);**

## DESCRIPTION

The **elf\_version** function sets libelf's ELF version to the specified value. This function must be called before any other libelf functions are used.

## PARAMETERS

- *version*

  An *unsigned int* value specifying the desired ELF version for the library.  This is should be set to **EV\_CURRENT** to indicate the current ELF version. At this time the only supported ELF version is **EV\_CURRENT**.

## RETURN VALUE

The **elf\_version** function returns **EV\_CURRENT** if *version* is supported and sets the library's ELF version to this value.  If the given *version* is **EV\_NONE**, then this function returns **EV\_CURRENT** and does not set the library's ELF version.  If the specified version is not supported, this function returns **EV\_NONE**.
