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. SEE ALSO
dwarf(3), dwarf_add_AT_location_expr(3), dwarf_add_expr_gen(3), dwarf_expr_current_offset(3), dwarf_expr_into_block(3), dwarf_new_expr(3) BSD
