Abstract: A version for each of a plurality of object files in a computer program is verified by identifying a version of an object file of the plurality of object files in the computer program and comparing the identified version to an initial version. In response to the identified version being different than the initial version, an alert is generated.

Abstract: The present invention is directed to a transparent method of correctly handling improper use of pointers. During the execution of programs, pointers are occasionally returned to the program and, if treated improperly, may adversely effect system operation resulting in termination of the program, a nonresponsive system or invalid or erroneous results. The present invention defines a safe pointer which supports standard pointer operations and performs pointer checking on each pointer returned to the executing program to determine whether its use is consistent with the pointer type. If the operation will not cause any error, the operation is allowed. If the operation will cause an error or other to undesirable operation, the operation is not permitted to be performed on the pointer and appropriate actions are taken.

Abstract: A system for rapidly and easily searching large collections of documents using standard web browser programs as the user interface. The present invention parses a collection of text documents to identify symbols therein and builds a database file which identifies the file and line locations of each symbol identified. The database file is constructed to permit rapid searching for symbols to permit interactive use of the present invention as a search tool. A database client process interacts with the web browser via standard CGI techniques to convert browser commands and queries into appropriate server process requests. A server process receives such requests and manipulates the database files in response to the requests. Query results returned to the client process are then reformatted by the client process to return a document with hypertext links in place of search keys located in the database (e.g., an HTML page).
