DWARF_ADD_ARANGE(3)					   BSD Library Functions Manual 				       DWARF_ADD_ARANGE(3)

NAME
dwarf_add_arange, dwarf_add_arange_b -- add address range information to a DWARF producer instance LIBRARY
DWARF Access Library (libdwarf, -ldwarf) SYNOPSIS
#include <libdwarf.h> Dwarf_Unsigned dwarf_add_arange(Dwarf_P_Debug dbg, Dwarf_Addr start, Dwarf_Unsigned length, Dwarf_Signed symbol_index, Dwarf_Error *err); Dwarf_Unsigned dwarf_add_arange_b(Dwarf_P_Debug dbg, Dwarf_Addr start, Dwarf_Unsigned length, Dwarf_Unsigned symbol_index, Dwarf_Unsigned end_symbol_index, Dwarf_Addr offset_from_end_symbol, Dwarf_Error *err); DESCRIPTION
Function dwarf_add_arange_b() adds an address range entry to a producer instance. Argument dbg should reference a DWARF producer instance allocated using dwarf_producer_init(3) or dwarf_producer_init_b(3). Argument start specifies the relocatable start address of the address range. Argument length specifies the length of the address range. Argument symbol_index specifies the ELF symbol index of the first symbol to be used for relocation. Argument end_symbol_index specifies the ELF symbol index of the second symbol to be used for relocation. o If argument end_symbol_index is not 0, the DW_DLC_SYMBOLIC_RELOCATIONS flag should have been set on the DWARF producer instance. The address value specified by argument start will be treated as an offset value from the first symbol, and the argument offset_from_end_symbol should hold an offset value from the second symbol. Application code can retrieve the relocation entries for the symbol pair by calling function dwarf_get_relocation_info(3). The relocation entry for the first symbol will have type dwarf_drt_first_of_length_pair and the relocation entry for the second symbol will have type dwarf_drt_second_of_length_pair. o If argument end_symbol_index is 0, argument offset_from_end_symbol will be ignored and only one symbol is used for relocation. If argument err is not NULL, it will be used to store error information in case of an error. Function dwarf_add_arange() is deprecated. It is similar to function dwarf_add_arange_b() except that it cannot handle all possible symbol index values and supports only one relocation symbol. RETURN VALUES
On success, these functions return a non-zero value. In case of an error, these functions return 0 and set the argument err. ERRORS
These functions can fail with: [DW_DLE_ARGUMENT] Argument dbg was NULL. [DW_DLE_ARGUMENT] Argument end_symbol_index was non-zero, but the flag DW_DLC_SYMBOLIC_RELOCATIONS was not set on the producer instance. [DW_DLE_MEMORY] An out of memory condition was encountered during the execution of the function. SEE ALSO

DWARF_ADD_AT_TARG_ADDRESS(3)				   BSD Library Functions Manual 			      DWARF_ADD_AT_TARG_ADDRESS(3)

NAME
dwarf_add_AT_targ_address, dwarf_add_AT_targ_address_b -- create and attach address class attributes LIBRARY
DWARF Access Library (libdwarf, -ldwarf) SYNOPSIS
#include <libdwarf.h> Dwarf_P_Attribute dwarf_add_AT_targ_address(Dwarf_P_Debug dbg, Dwarf_P_Die die, Dwarf_Half attr, Dwarf_Unsigned pc_value, Dwarf_Signed sym_index, Dwarf_Error *err); Dwarf_P_Attribute dwarf_add_AT_targ_address_b(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_targ_address_b() creates an attribute descriptor belonging to the 'address' class and attaches it to the debugging information entry referenced by argument die. The created attribute descriptor will have DWARF form DW_FORM_addr. If flag DW_DLC_SIZE_64 is set on the producer instance, the attribute value will be 8 bytes in size. Otherwise the attribute value will be 4 bytes in size. 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 should specify the attribute code of the created attribute descriptor. Argument pc_value should hold a relocatable address value which will become the value of the created attribute descriptor. Argument sym_index should specify the ELF symbol index of the symbol to be used for relocating the address value. If argument err is not NULL, it will be used to store error information in case of an error. Function dwarf_add_AT_targ_address() is deprecated. It is similar to function dwarf_add_AT_targ_address_b() except that it cannot handle all possible symbol index values. RETURN VALUES
On success, these functions return the created attribute descriptor. In case of an error, these functions return DW_DLV_BADADDR and sets the argument err. ERRORS
These functions 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. SEE ALSO
