The statistics record virtual memory usage since\rthe kernel was booted.\r<p>\rFor related information for a specific task, see the <strong>task_basic_info</strong>\rstructure.\r<h3>NOTES</h3>\r<p>\rThis structure is machine word length specific because of the memory sizes\rreturned.\r<h3>RELATED INFORMATION</h3>\r<p>\rFunctions:\r<a href="task_info.html"><strong>task_info</strong></a>,\r<a href="host_page_size.html"><strong>host_page_size</strong></a>. \r<p>\rData Structures:\r<a href="task_basic_info.html"><strong>task_basic_info</strong></a>.\r\r |
