DWARF_ADD_EXPR_ADDR(3)					   BSD Library Functions Manual 				    DWARF_ADD_EXPR_ADDR(3)

NAME

     dwarf_add_expr_addr, dwarf_add_expr_addr_b -- add a DW_OP_addr location expression

LIBRARY

     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS

     #include <libdwarf.h>

     Dwarf_Unsigned
     dwarf_add_expr_addr(Dwarf_P_Expr expr, Dwarf_Unsigned address, Dwarf_Signed sym_index, Dwarf_Error *err);

     Dwarf_Unsigned
     dwarf_add_expr_addr_b(Dwarf_P_Expr expr, Dwarf_Unsigned address, Dwarf_Unsigned sym_index, Dwarf_Error *err);

DESCRIPTION

     Function dwarf_add_expr_addr_b() adds a DW_OP_addr location expression to the location expression descriptor referenced by argument expr.

     Argument expr should reference a location expression descriptor allocated using the function dwarf_new_expr(3).

     Argument address specifies the operand, a relocatable address value.

     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.

     Function dwarf_add_expr_addr() is deprecated.  It is similar to function dwarf_add_expr_addr_b() except that it cannot handle all possible
     symbol index values.

RETURN VALUES

     On success, these functions return the size in bytes of the location expression byte stream generated.  In case of an error, these functions
     return DW_DLV_NOCOUNT and set the argument err.

ERRORS

     These functions can fail with:

     [DW_DLE_ARGUMENT]	Argument expr was NULL.

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

DWARF_ADD_AT_DATAREF(3) 				   BSD Library Functions Manual 				   DWARF_ADD_AT_DATAREF(3)

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.
