add bytes to the end

WARNING: this function has no bounds checks and so it's possible to overrun the buffer by calling this. We are not adding bounds check because we want

Selects the next TrafficClass to run.

Retrieves the next entry from the queue and in the process, potentially drops objects as well as changes between dropping state and not dropping state

Find the pointer to the stored value by the key. Return nullptr if not exist.

Run a command. If quiet is True, or if V is not set in the environment, eat its stdout and stderr by default (we'll print both to stderr

Runs the scheduler once.

Private methods, for use by PortBuilder.

The user is responsible for creating and eventually deleting the file.

Copies "bytes" data from "src" to "dst". Same as memcpy() and rte_memcpy(), but significantly faster for both aligned/unaligned buffers. Performs best

Inline version of Copy(). Use only when performance is critial. Since the function is inlined whenever used, the compiled code will be substantially l

Set the `idx`th field of this table to one at offset `offset` bytes into a buffer with length `size` and mask `mask`. Returns 0 on success, non-zero e

returns [0, range) with no integer modulo operation */

Returns internet checksum (the negative of 16-bit one's complement sum) of 'len' bytes from 'buf'

* Breaks up the stored fd into (fd, generation) pair. * Note: the returned fd may be kNotOpen. */

Returns false if there's no pcap binding established

* l2_init: * Initilizes the l2_table. * It creates the slots of MAX_TABLE_SIZE multiplied by MAX_BUCKET_SIZE. * * @l2tbl: pointer to * @size: n

Returns IP checksum of the ip header 'iph' without ip options It skips the checksum field into the calculation It does not set the checksum field in i

Returns TCP (on IPv4) checksum of the tcp header 'tcph' with pseudo header informations - source ip ('src'), destiniation ip ('dst'), and tcp byte str

Remove the stored entry by the key Return false if not exist.

Requires that the next received string is what we expect.

Send message to parent or child, figuring out which way automatically.

Return the number of stored entries

* Return the number of entries in a ring. * * @param r * A pointer to the ring structure. * @return * The number of entries in the ring. */

Fold a 32-bit non-inverted checksum into a inverted 16-bit one, which can be readily written to L3/L4 checksum field

Returns updated checksum value, which is ready to be written in the header

Return current time in seconds since the Epoch. * This is consistent with Python's time.time() */
