| Abstract | Embedded applications with a long running life time particularly require a high degree of reliability. Many types of weaknesses residing in software can reduce the reliability, but memory leaks are prominent sources of software weaknesses for long running applications. As memory leaks are typically cumbersome and illusive, finding their sources demands programmers to make a huge effort even with fairly automated memory leak detection tools. Recently, dynamic detectors with light overheads have been emerged. They use sampling-based techniques to reduce overheads. According to the frequencies of code executions and data accesses, the memory monitor adaptively controls the sampling periods. The accuracies of existing sampling techniques are, however, unsatisfactory in some cases. In this paper, we present a more accurate memory leak detection technique, which takes advantage of context information. Our memory leak detector, which is also based on data sampling, adopts a notion of context (or call path) to sort out dynamically allocated memories and more accurately tracks the sources of memory leaks in the source code. Our experiments with SPEC CINT2000 benchmarks show our technique finds more memory leaks by up to 72% with comparable overheads to the existing data sampling technique. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
