DESCRIPTION

ldns_rdf_new() allocates a new rdf structure and fills it. This function DOES NOT copy the contents from the buffer, unlinke 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, unlinke 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 presenta‐ tion format) output: the file stream to print to rdf: the rdata field to print Returns void
