ldns(3) Library Functions Manual ldns(3)

# [NAME](#NAME)

ldns\_rdf\_size, ldns\_rdf\_get\_type, ldns\_rdf\_data, ldns\_rdf\_compare - get rdf attributes

# [SYNOPSIS](#SYNOPSIS)

#include <stdint.h>  
#include <stdbool.h>

#include <ldns/ldns.h>

size\_t ldns\_rdf\_size(const ldns\_rdf \*rd);

ldns\_rdf\_type ldns\_rdf\_get\_type(const ldns\_rdf \*rd);

uint8\_t* ldns\_rdf\_data(const ldns\_rdf \*rd);

int ldns\_rdf\_compare(const ldns\_rdf \*rd1, const ldns\_rdf \*rd2);

# [DESCRIPTION](#DESCRIPTION)

*ldns\_rdf\_size*() returns the size of the rdf.  
**\*rd**: the rdf to read from  
Returns uint16\_t with the size

*ldns\_rdf\_get\_type*() returns the type of the rdf. We need to insert \_get_ here to prevent conflict the rdf\_type TYPE.  
**\*rd**: the rdf to read from  
Returns ldns\_rdf\_type with the type

*ldns\_rdf\_data*() returns the data of the rdf.  
**\*rd**: the rdf to read from

Returns uint8\_t* pointer to the rdf's data

*ldns\_rdf\_compare*() compares two rdf's on their wire formats. (To order dnames according to rfc4034, use ldns\_dname\_compare)  
**rd1**: the first one  
**rd2**: the second one  
Returns 0 if equal  
Returns -1 if rd1 comes before rd2  
Returns +1 if rd2 comes before rd1
