NAME
          irQueryXferAllow, irQueryXferDeny - query transfer security
          allow/deny tables

     SYNOPSIS
          #include <irapi-ad.h>

          int irQueryXferAllow(const char*extension_string);

          int irQueryXferDeny(const char*extension_string);

     DESCRIPTION
          The irQueryXfer functions allow an application to check if
          an extension extension_string is valid for transfer.  The
          irQueryXferAllow and irQueryXferDeny functions read the
          Transfer security allow and deny, respectively, to see if
          the extension_string in the query is within the threshold of
          one of the entries in the table.

     RETURN VALUE
          IRR_OK is returned if the request is successful.

          IRR_FAIL is returned if an error occurs.

     ERROR
          irError is set as follows if an error occurs:

          IRER_INVALID if an invalid argument is passed in

          IRER_NOTFOUND if no entry is found that covers the
          extension_string

          IRER_SYSERROR if a system error occurred (check irSysError
          for additional information)
