NAME

Net::DNS::ToolKit::Question - Resource Handler

SYNOPSIS

  DO NOT use Net::DNS::ToolKit::Question
  DO NOT require Net::DNS::ToolKit::Question

  Net::DNS::ToolKit::Question is autoloaded by
  class Net::DNS::ToolKit::RR and its methods
  are instantiated in a 'special' manner.

DESCRIPTION

($newoff,$name,$type,$class) = $get->Question(\$buffer,$offset);

Get question from $buffer. Returns the expanded name, type and class.

  input:        pointer to buffer,
                offset into buffer
  returns:      new offset,
                expanded name,
                type,
                class

($newoff,@dnptrs) = $put->Question(\$buffer,$offset, $name,$type,$class,\@dnptrs);
Append a question to the $buffer. Returns a new pointer array for compressed names and the offset to the next RR.

NOTE: it is up to the user to update the question count. See: put_qdcount

Since the question usually is the first record to be appended to the buffer, @dnptrs may be ommitted. See the details at dn_comp.

Usage: ($newoff,@dnptrs)=$put->Question(\$buffer,$offset, $name,$type,$class);
```
  input:        pointer to buffer,
                offset into buffer,
                domain name,
                question type,
                question class,
                pointer to array of
                  previously compressed names,
  returns:      offset to next record,
                updated array of offsets to
                  previous compressed names
```

($name,$typeTXT,$classTXT) = $parse->Question($name,$type,$class);

Convert non-printable and numeric data into ascii text.

  returns:      domain name,
