◆ dwarf_attrlist()

int dwarf_attrlist	(	Dwarf_Die	dw_die,
		Dwarf_Attribute **	dw_attrbuf,
		Dwarf_Signed *	dw_attrcount,
		Dwarf_Error *	dw_error
	)

Parameters

dw_die	The DIE from which to pull attributes.
dw_attrbuf	The pointer is set to point to an array of Dwarf_Attribute (pointers to attribute data). This array must eventually be deallocated.
dw_attrcount	The number of entries in the array of pointers. There is no null-pointer to terminate the list, use this count.
dw_error	A place to return error details.

Returns: If it returns DW_DLV_ERROR and dw_error is non-null it creates an Dwarf_Error and places it in this argument. Usually returns DW_DLV_OK.

		Dwarf_Error *	dw_error
	)

Parameters

dw_attr	The Dwarf_Attribute of interest.
dw_form	The DW_FORM you are asking about, DW_FORM_strp for example.

int dwarf_whatform	(	Dwarf_Attribute	dw_attr,
		Dwarf_Half *	dw_returned_final_form,
		Dwarf_Error *	dw_error
	)

Parameters

dw_error	A place to return error details.

Returns: Returns DW_DLV_OK and sets dw_returned_final_form If attribute is passed in NULL or the attribute is badly broken the call returns DW_DLV_ERROR. Never returns DW_DLV_NO_ENTRY;

◆ dwarf_whatform_direct()

int dwarf_whatform_direct	(	Dwarf_Attribute	dw_attr,
		Dwarf_Half *	dw_returned_initial_form,
		Dwarf_Error *	dw_error
	)

Parameters

dw_attr	The Dwarf_Attribute of interest.

◆ dwarf_whatattr()

int dwarf_whatattr	(	Dwarf_Attribute	dw_attr,

	)

Parameters

dw_attr	The Dwarf_Attribute of interest.
dw_returned_attrnum	The attribute number of the attribute is returned through the pointer. For example, DW_AT_name
dw_error	A place to return error details.

Returns: Returns DW_DLV_OK and sets dw_returned_attrnum If attribute is passed in NULL or the attribute is badly broken the call returns DW_DLV_ERROR. Never returns DW_DLV_NO_ENTRY;

◆ dwarf_formref()

int dwarf_formref	(	Dwarf_Attribute	dw_attr,
		Dwarf_Off *	dw_return_offset,
		Dwarf_Bool *	dw_is_info,
		Dwarf_Error *	dw_error
	)

The DW_FORM of the attribute must be one of a small set of local reference forms: DW_FORM_ref<n> or DW_FORM_udata.

Parameters

dw_attr	The Dwarf_Attribute of interest.
dw_return_offset	Returns the CU-relative offset through the pointer.
dw_is_info	Returns a flag through the pointer. TRUE if the offset is in .debug_info, FALSE if it is in .debug_types
dw_error	A place to return error details.

Returns: Returns DW_DLV_OK and sets dw_returned_attrnum If attribute is passed in NULL or the attribute is badly broken or the FORM of this attribute is not one of the small set of local references the call returns DW_DLV_ERROR. Never returns DW_DLV_NO_ENTRY;

int dwarf_global_formref_b	(	Dwarf_Attribute	dw_attr,
		Dwarf_Off *	dw_return_offset,
		Dwarf_Bool *	dw_offset_is_info,
		Dwarf_Error *	dw_error
	)

The target section of the returned offset can be in various sections depending on the FORM. Only a DW_FORM_ref_sig8 can change the returned offset of a .debug_info DIE via a lookup into .debug_types by changing dw_offset_is_info to FALSE (DWARF4).

The caller must determine the target section from the FORM.

Parameters

dw_attr	The Dwarf_Attribute of interest.
dw_return_offset	Returns the CU-relative offset through the pointer.
dw_offset_is_info	For references to DIEs this informs whether the target DIE (the target the offset refers to) is in .debug_info or .debug_types. For non-DIE targets this field is not meaningful. Refer to the attribute FORM to determine the target section of the offset.
dw_error	A place to return error details.

Returns: Returns DW_DLV_OK and sets dw_return_offset and dw_offset_is_info. If attribute is passed in NULL or the attribute is badly broken or the FORM of this attribute is not one of the many reference types the call returns DW_DLV_ERROR. Never returns DW_DLV_NO_ENTRY;

◆ dwarf_global_formref()

int dwarf_global_formref	(	Dwarf_Attribute	dw_attr,
		Dwarf_Off *	dw_return_offset,
		Dwarf_Error *	dw_error
	)

See also: dwarf_global_formref_b

This is the same, except there is no dw_offset_is_info pointer so in the case of DWARF4 and DW_FORM_ref_sig8 it is not possible to determine which section the offset applies to!
