NAME

     dwarf_add_AT_ref_address -- create a reference class attribute descriptor

LIBRARY

     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS

     #include <libdwarf.h>

     Dwarf_P_Attribute
     dwarf_add_AT_ref_address(Dwarf_P_Debug dbg, Dwarf_P_Die die, Dwarf_Half attr, Dwarf_Unsigned pc_value, Dwarf_Unsigned sym_index,
	 Dwarf_Error *err);

DESCRIPTION

     Function dwarf_add_AT_ref_address() creates a 'reference' class attribute descriptor containing a relocatable address value.  The created
     attribute will use DWARF form DW_FORM_ref_addr.

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

     Argument die should reference a debugging information entry allocated using dwarf_new_die(3).

     Argument attr specifies the attribute code of the created attribute.

     Argument pc_value contains a relocatable address which will become the value of the created attribute.

     Argument sym_index should specify the ELF symbol index of the symbol to be used when relocating the address value.

     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_add_AT_ref_address() returns the created attribute descriptor.	In case of an error, function
     dwarf_add_AT_ref_address() returns DW_DLV_BADADDR and sets the argument err.

ERRORS

     Function dwarf_add_AT_ref_address() can fail with:

     [DW_DLE_ARGUMENT]	Either of the arguments dbg or die was NULL.

     [DW_DLE_MEMORY]	An out of memory condition was encountered during execution.

NAME

     dwarf_add_AT_dataref -- create an attribute descriptor for a relocatable address

LIBRARY

     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS

     #include <libdwarf.h>

     Dwarf_P_Attribute
     dwarf_add_AT_dataref(Dwarf_P_Debug dbg, Dwarf_P_Die die, Dwarf_Half attr, Dwarf_Unsigned pc_value, Dwarf_Unsigned sym_index,
	 Dwarf_Error *err);

DESCRIPTION

     Function dwarf_add_AT_dataref() creates an attribute descriptor for a relocatable address and attaches it to the debugging information entry
     referenced by argument die.

     If flag DW_DLC_SIZE_64 is set, the address value will be 8 bytes in size and of the DWARF form DW_FORM_data8.  Otherwise, the address value
     will be 4 bytes in size and of the DWARF form DW_FORM_data4.

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

     Argument die should reference a debugging information entry allocated using dwarf_new_die(3).

     Argument attr specifies the attribute code of the created attribute descriptor.

     Argument pc_value specifies the value of the relocatable address.

     Argument sym_index specifies the ELF symbol index of the 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_add_AT_dataref() returns the created attribute descriptor.  In case of an error, function dwarf_add_AT_dataref()
     returns DW_DLV_BADADDR and sets the argument err.

ERRORS

     Function dwarf_add_AT_dataref() can fail with:

     [DW_DLE_ARGUMENT]	Either of the arguments dbg or die was NULL.

     [DW_DLE_MEMORY]	An out of memory condition was encountered during the execution of the function.
