Memory resource allocation look ahead system and method

摘要

A memory resource allocation look ahead system is implemented in event logger (14), operating in conjunction with one or more event sinks (18). When the event logger (14) is called, all information in the argument fist is copied into an event buffer maintained by the logger (14), and the buffer is placed at the input end of queue (44). The event sinks 18 contain a similar queue. In operation of the event logger 14, an evd-get-event routine is used to obtain event reports from the event queue (44). The evd-get-event routine includes a next-size-hint argument, giving the size of the event record that will be obtained with the next call to evd-get-event. The next-size-hint argument is used to allocate memory for the next call to evd-get-event.
