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 ex-
     pression byte stream generated.  In case of an error, these functions re-
     turn 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.
