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

DWARF_ADD_AT_LOCATION_EXPR(3)				   BSD Library Functions Manual 			     DWARF_ADD_AT_LOCATION_EXPR(3)

NAME
dwarf_add_AT_location_expr -- create an attribute descriptor for a location expression LIBRARY
DWARF Access Library (libdwarf, -ldwarf) SYNOPSIS
#include <libdwarf.h> Dwarf_P_Attribute dwarf_add_AT_location_expr(Dwarf_P_Debug dbg, Dwarf_P_Die die, Dwarf_Half attr, Dwarf_P_Expr loc_expr, Dwarf_Error *err); DESCRIPTION
Function dwarf_add_AT_location_expr() creates an attribute descriptor for a location expression and attaches it to the debugging information entry referenced by argument die. 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 loc_expr should reference a location expression descriptor allocated using dwarf_new_expr(3). The attribute created by function dwarf_add_AT_location_expr() will have one of the DWARF forms DW_FORM_block, DW_FORM_block1, DW_FORM_block2 or DW_FORM_block4, depending on the size of the byte stream generated by the location expression descriptor referenced by argument loc_expr. If argument err is not NULL, it will be used by to store error information in case of an error. RETURN VALUES
On success, function dwarf_add_AT_location_expr() returns the created attribute descriptor. In case of an error, function dwarf_add_AT_location_expr() returns DW_DLV_BADADDR and sets the argument err. ERRORS
Function dwarf_add_AT_location_expr() can fail with: [DW_DLE_ARGUMENT] One of the arguments dbg, die or loc_expr was NULL. [DW_DLE_MEMORY] An out of memory condition was encountered during the execution of the function. SEE ALSO
