To solve this problem, there is the file operation mechanism, which shares the data of file between many processes. This representative mechanism is memory mapped file. However, memory mapped file can not change size of file. To solve this problem, we propose advanced memory mapped file that can change size of file. This paper presents the implementation of advanced memory mapped file which is applied to the AnT operating system, and the evaluation which compares the overhead of the file operation between the AnT operating system and FreeBSD(6.3-RELEASE).","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告システムソフトウェアとオペレーティング・システム（OS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2012-04-30","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"4","bibliographicVolumeNumber":"2012-OS-121"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"created":"2025-01-18T23:35:53.399324+00:00","updated":"2025-01-21T19:14:43.014392+00:00"}
