摘要
A synchronization arrangement provides writer and reader entities access to an information resource, such as a trace buffer, located in a registry of a computer. The arrangement comprises a counter upon which atomic increments are performed to allocate entries of the trace buffer for temporarily storing trace message fragments provided by the writer entities. The arrangement also comprises reassembly queues for temporarily storing the message fragments sequentially retrieved from the trace buffer by the reader entities.
