 Takes in an ordinal from the Export Ordinal Table (see getExportOrdinal). This ordinal is biased by getOrdinalBase; however, the subtraction described in the documentation is done internally for convenience. Returns an address that is in one of two formats. If the address specified is not within the export section (as defined by the address and length indicated in the Optional Header), the field is an Export RVA: an actual address in code or data. Otherwise, the field is a Forwarder RVA, which names a symbol in another DLL. 
 An Export RVA is the address of the exported symbol when
loaded into memory, relative to the image base. For example, the
address of an exported function. 
 A Forwarder RVA is a pointer to a null-terminated ASCII
string in the export section, giving the DLL name and the name
of the export (for example, "MYDLL.expfunc") or the DLL
name and an export (for example, "MYDLL.#27"). 
 NOTE: the value returned has been transformed from an RVA to
a file pointer which can be added to the image base to find an
absolute address for the symbol.
