  -Following logic is applied for NULL view fields when printing:
  -
  -...
  +When array fields are printed, if they have "C" count indicator, then this number of fields
  +are printed (i.e. may be printed less fields than actually defined in array). If "L" length
  +indicator is present for field definition for carray type, then only number of bytes set in
  +lenght indictor is printed.
   
   
   RETURN VALUE
   ------------
  -On success, *Bgetr()* and *Bgetrv()* return zero; on error, -1 is returned, with *Berror* set to 
  -indicate the error.
  +On success, *Bvprint()*, *Bvfprint()* and *Bvfprintcb()* return zero; on error, 
  +-1 is returned, with *Berror* set to indicate the error.
   
   ERRORS
   ------
   Note that *Bstrerror()* returns generic error message plus custom message with 
  -debug info from last function call. Function my return errors from *Bfind(3)* and
  -corresponding mapped operation, e.g. *Bget(3)*, *Bfind(3)*, etc.
  +debug info from last function call.
   
   Following additional errors may be returned by this function:
   
  
positive.code: 
  int Bvfprint (char * 'cstruct', char * 'view', FILE * 'outf');
  
  int Bvfprintcb (char * 'cstruct', char * 'view', ndrx_plugin_tplogprintubf_hook_t 'p_writef', void *'dataptr1');
  
  
  Link with '-lubf -lnstd -lm -lpthread'
  
negative.code: indicates the data length in the 'buffer', this includes a newline and EOS byte.
  'dataptr1' is forwarded from the *Bvfprintcb()* call to callback. Parameters:
  'do_write', 'outf' are not used. 'fid' is set field number starting from *0* which
  is being printed. On return callback function shall return *0* in case of success.
  In case of failure, non *0* value shall be returned.
  
  Data format for printing to *stdout* or *FILE* stream is following:
  "<FIELD><TAB><VALUE><NEW_LINE>". When printing to callback, additionally EOS (0x00)
