Member Function Documentation

void folly::SendMsgDataCallback::getAncillaryData ( folly::WriteFlags  , void *    )

inlineoverridevirtualnoexcept

getAncillaryData() will be invoked to initialize ancillary data buffer referred by "msg_control" field of msghdr structure passed to sendmsg() system call. The function assumes that the size of buffer is not smaller than the value returned by getAncillaryDataSize() method for the same combination of flags.

Parameters

flags	Write flags requested for the given write operation
data	Pointer to ancillary data buffer to initialize.

Reimplemented from folly::SendMsgParamsCallbackBase.

uint32_t folly::SendMsgDataCallback::getAncillaryDataSize ( folly::WriteFlags  )

inlineoverridevirtualnoexcept

getAncillaryDataSize() will be invoked to retrieve the size of ancillary data buffer which should be passed to sendmsg() system call

Parameters

flags

Write flags requested for the given write operation
