# [DESCRIPTION](#DESCRIPTION)

*ldns\_rdf\_new*() allocates a new rdf structure and fills it. This function DOES NOT copy the contents from the buffer, unlike ldns\_rdf\_new\_frm\_data()  
**type**: type of the rdf  
**size**: size of the buffer  
**data**: pointer to the buffer to be copied  
Returns the new rdf structure or NULL on failure

*ldns\_rdf\_clone*() clones a rdf structure. The data is copied.  
**rd**: rdf to be copied  
Returns a new rdf structure

*ldns\_rdf\_new\_frm\_data*() allocates a new rdf structure and fills it. This function \_does_ copy the contents from the buffer, unlike ldns\_rdf\_new()  
**type**: type of the rdf  
**size**: size of the buffer  
**data**: pointer to the buffer to be copied  
Returns the new rdf structure or NULL on failure

*ldns\_rdf\_new\_frm\_str*() creates a new rdf from a string.  
**type**: type to use  
**str**: string to use  
Returns ldns\_rdf* or NULL in case of an error

*ldns\_rdf\_new\_frm\_fp*() creates a new rdf from a file containing a string.  
**r**: the new rdf  
**type**: type to use  
**fp**: the file pointer to use  
Returns LDNS\_STATUS\_OK or the error

*ldns\_rdf\_free*() frees a rdf structure, leaving the data pointer intact.  
**rd**: the pointer to be freed  
Returns void

*ldns\_rdf\_deep\_free*() frees a rdf structure \_and_ frees the data. rdf should be created with \_new\_frm\_data  
**rd**: the rdf structure to be freed  
Returns void

*ldns\_rdf\_print*() Prints the data in the rdata field to the given file stream (in presentation format)

**output**: the file stream to print to  
**rdf**: the rdata field to print  
Returns void
