DWARF_ADD_AT_REF_ADDRESS(3)				   BSD Library Functions Manual 			       DWARF_ADD_AT_REF_ADDRESS(3)

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. SEE ALSO

NAME
dwarf_add_AT_const_value_signedint, dwarf_add_AT_const_value_string, dwarf_add_AT_const_value_unsignedint -- create and attach a DW_AT_const_value attribute LIBRARY
DWARF Access Library (libdwarf, -ldwarf) SYNOPSIS
#include <libdwarf.h> Dwarf_P_Attribute dwarf_add_AT_const_value_signedint(Dwarf_P_Die die, Dwarf_Signed value, Dwarf_Error *err); Dwarf_P_Attribute dwarf_add_AT_const_value_string(Dwarf_P_Die die, char *str, Dwarf_Error *err); Dwarf_P_Attribute dwarf_add_AT_const_value_unsignedint(Dwarf_P_Die die, Dwarf_Unsigned value, Dwarf_Error *err); DESCRIPTION
These functions create a DW_AT_const_value attribute descriptor and attach it to the debugging information entry referenced by argument die. Argument die should reference a debugging information entry allocated using dwarf_new_die(3). Function dwarf_add_AT_const_value_signedint() creates a DW_AT_const_value attribute descriptor containing the signed value specified by argu- ment value. The created attribute descriptor will have DWARF form DW_FORM_sdata. Function dwarf_add_AT_const_value_unsignedint() creates a DW_AT_const_value attribute descriptor containing the unsigned value specified by argument value. The created attribute descriptor will have DWARF form DW_FORM_udata. Function dwarf_add_AT_const_value_string() creates a DW_AT_const_value attribute descriptor containing the string pointed to by the NUL-ter- minated argument str. The created attribute descriptor will have DWARF form DW_FORM_strp. If argument err is not NULL, it will be used by these functions to store error information in case of an error. RETURN VALUES
On success, these functions return the created attribute descriptor. In case of an error, these functions return DW_DLV_BADADDR and set the argument err. ERRORS
These functions can fail with: [DW_DLE_ARGUMENT] Either of the arguments die or str was NULL. [DW_DLE_MEMORY] An out of memory condition was encountered during execution. SEE ALSO
