Waits for this socket to change status.
If interest=kRead, the socket will be watched to see if characters become available for reading; if interest=kWrite the socket will be watched to see if a write will not block. The argument 'timeout' specifies a maximum time to wait in millisec. Default no timeout. Returns 1 if a change of status of interest has been detected within timeout; 0 in case of timeout; < 0 if an error occured.

Send a status and a single message opcode.
Use kind (opcode) to set the TMessage "what" field. Returns the number of bytes that were sent (always 2*sizeof(Int_t)) and -1 in case of error. In case the kind has been or'ed with kMESS_ACK, the call will only return after having received an acknowledgement, making the sending process synchronous.

Send an object.
Returns the number of bytes sent and -1 in case of error. In case the "kind" has been or'ed with kMESS_ACK, the call will only return after having received an acknowledgement, making the sending synchronous.

Check if TProcessIDs must be sent.
The list of TProcessIDs in the object in the message is found by looking in the TMessage bits. We send only the TProcessIDs not yet send on this socket.

Send a raw buffer of specified length.
Using option kOob one can send OOB data. Returns the number of bytes sent or -1 in case of error. Returns -4 in case of kNoBlock and errno == EWOULDBLOCK. Returns -5 if pipe broken or reset by peer (EPIPE || ECONNRESET).

Check if TStreamerInfo must be sent.
The list of TStreamerInfo of classes in the object in the message is in the fInfos list of the message. We send only the TStreamerInfos not yet sent on this socket.

void TUDPSocket::SetCompressionSettings | ( | Int_t | settings = ROOT::RCompressionSetting::EDefaults::kUseGeneralPurpose | ) |
Used to specify the compression level and algorithm: settings = 100 * algorithm + level.
level = 0, objects written to this file will not be compressed. level = 1, minimal compression level but fast. .... level = 9, maximal compression level but slower and might use more memory. (For the currently supported algorithms, the maximum level is 9) If compress is negative it indicates the compression level is not set yet.
The enumeration ROOT::RCompressionSetting::EAlgorithm associates each algorithm with a number. There is a utility function to help to set the value of the argument. For example, ROOT::CompressionSettings(ROOT::kLZMA, 1) will build an integer which will set the compression to use the LZMA algorithm and compression level 1. These are defined in the header file Compression.h.
Note that the compression settings may be changed at any time. The new compression settings will only apply to branches created or attached after the setting is changed and other objects written after the setting is changed.
