# [DESCRIPTION](#DESCRIPTION)

*ldns\_native2rdf\_int8*() returns the rdf containing the native uint8\_t repr.  
**type**: the ldns\_rdf type to use  
**value**: the uint8\_t to use  
Returns ldns\_rdf* with the converted value

*ldns\_native2rdf\_int16*() returns the rdf containing the native uint16\_t representation.  
**type**: the ldns\_rdf type to use  
**value**: the uint16\_t to use  
Returns ldns\_rdf* with the converted value

*ldns\_native2rdf\_int32*() returns an rdf that contains the given int32 value.

Because multiple rdf types can contain an int32, the type must be specified  
**type**: the ldns\_rdf type to use  
**value**: the uint32\_t to use  
Returns ldns\_rdf* with the converted value

*ldns\_native2rdf\_int16\_data*() returns an int16\_data rdf that contains the data in the given array, preceded by an int16 specifying the length.

The memory is copied, and an LDNS\_RDF\_TYPE\_INT16DATA is returned  
**size**: the size of the data  
**\*data**: pointer to the actual data

Returns ldns\_rd* the rdf with the data

*ldns\_rdf2native\_int8*() returns the native uint8\_t representation from the rdf.  
**rd**: the ldns\_rdf to operate on  
Returns uint8\_t the value extracted

*ldns\_rdf2native\_int16*() returns the native uint16\_t representation from the rdf.  
**rd**: the ldns\_rdf to operate on  
Returns uint16\_t the value extracted

*ldns\_rdf2native\_int32*() returns the native uint32\_t representation from the rdf.  
**rd**: the ldns\_rdf to operate on  
Returns uint32\_t the value extracted

*ldns\_rdf2native\_sockaddr\_storage*() returns the native sockaddr representation from the rdf.  
**rd**: the ldns\_rdf to operate on  
**port**: what port to use. 0 means; use default (53)  
**size**: what is the size of the sockaddr\_storage  
Returns struct sockaddr* the address in the format so other functions can use it (sendto)

*ldns\_rdf2native\_time\_t*() returns the native time\_t representation from the rdf.  
**rd**: the ldns\_rdf to operate on  
Returns time\_t the value extracted (32 bits currently)
