Pure Software's Object Code Insertion technology (OCI)
Purify Data Sheet
Identifies execution errors and memory leaks within your application everywhere
they occur.
Enables developers to eliminate run-time problems before they reach the
end-user.
Improves productivity and reduces training time by presenting all information in
an easy to use and understand interface.
For today's complex software development projects, run-time or memory access
errors are some of the most difficult problems to solve. Reading or writing past
the boundary of an array, leaking memory unpredictably, using uninitialized
memory with random contents; these potentially disastrous errors may take weeks
to find and fix. Purify solves these problem by combining the most comprehensive
run-time error checking available with an easy to use graphical user interface.
To achieve comprehensive checking Purify uses Object Code Insertion (OCI)
technology to intercept memory accesses by inserting additional instructions in
the object code before every Load and Store operation. The major advantage of
OCI is completeness: all of the code, including thirdparty and shared libraries
can be checked in this manner. Even hand-optimized assembly code can be checked.
OCI helps Purify find more types of errors in more areas of your application
than any other similar tool.
This completeness means bugs in application code that manifest themselves in
vendor or third-party libraries are detected.
By adding one word, purify, to the application's makefile, Purify's automatic
checking begins. A Purify'd program is a standard executable that can be fork'd,
exec'd or run under a debugger.
Purify offers both interactive and batch reporting of error messages to make
analysis as convenient as possible. An intuitive Graphical User Interface (GUI) allows the user to
browse error messages more efficiently than ever before. The hierarchical, or
outline display, provides detailed information for specific error messages
enabling the user to focus on the most critical errors first. Access to
application source or development processes such as Run, Make and Debug are only a mouse click away. This instant
access makes correcting application errors simple and easy.
