Shell script reports an error "unary operator expected" pointing the above line.

Please can some one let me know what is missing.

DWARF_HIGHPC(3) BSD Library Functions Manual DWARF_HIGHPC(3)
NAME
dwarf_arrayorder, dwarf_bitoffset, dwarf_bitsize, dwarf_bytesize, dwarf_highpc, dwarf_highpc_b, dwarf_lowpc, dwarf_srclang -- retrieve the
value of a DWARF attribute
LIBRARY
DWARF Access Library (libdwarf, -ldwarf)
SYNOPSIS
#include <libdwarf.h>
int
dwarf_arrayorder(Dwarf_Die die, Dwarf_Unsigned *ret_order, Dwarf_Error *err);
int
dwarf_bitoffset(Dwarf_Die die, Dwarf_Unsigned *ret_size, Dwarf_Error *err);
int
dwarf_bitsize(Dwarf_Die die, Dwarf_Unsigned *ret_size, Dwarf_Error *err);
int
dwarf_bytesize(Dwarf_Die die, Dwarf_Unsigned *ret_size, Dwarf_Error *err);
int
dwarf_highpc(Dwarf_Die die, Dwarf_Addr *ret_highpc, Dwarf_Error *err);
int
dwarf_highpc_b(Dwarf_Die die, Dwarf_Addr *ret_highpc, Dwarf_Half *ret_form, enum Dwarf_Form_Class *ret_class, Dwarf_Error *err);
int
dwarf_lowpc(Dwarf_Die die, Dwarf_Addr *ret_lowpc, Dwarf_Error *err);
int
dwarf_srclang(Dwarf_Die die, Dwarf_Unsigned *ret_lang, Dwarf_Error *err);
DESCRIPTION
These convenience functions are used to retrieve DWARF attribute values associated with a Debugging Information Entry (DIE) descriptor
denoted by argument die. These functions store the value of the requested attribute into the location pointed to by their second argument,
provided that the requested attribute exists in the debugging information entry.
The list of functions and the DWARF attribute that they retrieve are:
dwarf_arrayorder() Retrieve the DW_AT_ordering attribute value.
dwarf_bitoffset() Retrieve the DW_AT_bit_offset attribute value.
dwarf_bitsize() Retrieve the DW_AT_bit_size attribute value.
dwarf_bytesize() Retrieve the DW_AT_byte_size attribute value.
dwarf_highpc() Retrieve the DW_AT_high_pc attribute value.
dwarf_highpc_b() Retrieve the DW_AT_high_pc attribute value.
dwarf_lowpc() Retrieve the DW_AT_low_pc attribute value.
dwarf_srclang() Retrieve the DW_AT_language attribute value.
Function dwarf_highpc_b() is an enhanced version of function dwarf_highpc(). It sets the location specified by argument ret_form to the form
code of the attribute DW_AT_high_pc, and sets the location specified by argument ret_class to the class of that form. A value of NULL may be
used for either of the arguments ret_form or ret_class if the caller is not interested in the respective value.
RETURN VALUES
These functions return DW_DLV_OK on success.
If the debugging information entry descriptor denoted by argument die does not contain the requested attribute, these functions return
DW_DLV_NO_ENTRY and set argument err. For other errors, they return DW_DLV_ERROR and set argument err.
ERRORS
These functions can fail with the following errors:
[DW_DLE_ARGUMENT] Arguments die, ret_highpc, ret_lowpc, ret_size, ret_lang or ret_order were NULL.
[DW_DLE_NO_ENTRY] Argument die had no requested attribute.
