# NAME

`dwarf_lne_set_address` — set the base address for line number information

# LIBRARY

DWARF Access Library (libdwarf, -ldwarf)

# SYNOPSIS

`#include <libdwarf.h>`

Dwarf_Unsigned
`dwarf_lne_set_address`(Dwarf_P_Debug dbg, Dwarf_Addr off, Dwarf_Unsigned symndx, Dwarf_Error *err);

# DESCRIPTION

Function `dwarf_lne_set_address`() sets the base address used by subsequent invocations of the dwarf_add_line_entry(3) function.

Argument dbg should reference a DWARF producer instance allocated using dwarf_producer_init(3) or dwarf_producer_init_b(3).

Argument off specifies a relocatable program address.

Argument symndx specifies the index of the ELF symbol to be used for relocation.

If argument err is not `NULL`, it will be used to store error information in case of an error.

# RETURN VALUES

On success, function `dwarf_lne_set_address`() returns `DW_DLV_OK`. In case of an error, function `dwarf_lne_set_address`() returns `DW_DLV_NOCOUNT` and sets the argument err.

# ERRORS

Function `dwarf_lne_set_address`() can fail with:

[`DW_DLE_ARGUMENT`]
  Argument dbg was `NULL`.
[`DW_DLE_ARGUMENT`]
  The argument symndx had an illegal value.
[`DW_DLE_MEMORY`]
  An out of memory condition was encountered during the execution of the function.
