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() .br type: type of the rdf .br size: size of the buffer .br data: pointer to the buffer to be copied .br Returns the new rdf structure or NULL on failure

ldns_rdf_clone(): clones a rdf structure. The data is copied. .br rd: rdf to be copied .br 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() .br type: type of the rdf .br size: size of the buffer .br data: pointer to the buffer to be copied .br Returns the new rdf structure or NULL on failure

ldns_rdf_new_frm_str(): creates a new rdf from a string. .br type: type to use .br str: string to use .br 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. .br r: the new rdf .br type: type to use .br fp: the file pointer to use .br Returns LDNS_STATUS_OK or the error

ldns_rdf_free(): frees a rdf structure, leaving the data pointer intact. .br rd: the pointer to be freed .br Returns void

ldns_rdf_deep_free(): frees a rdf structure _and_ frees the data. rdf should be created with _new_frm_data .br rd: the rdf structure to be freed .br Returns void

ldns_rdf_print(): Prints the data in the rdata field to the given file stream (in presentation format)
.br output: the file stream to print to .br rdf: the rdata field to print .br Returns void
