I wanted to try STXXL to find how efficient it is in reading a big data file from the disk. So i setup the enviornment for using it. Then i ran this program http://algo2.iti.kit.edu/dementiev/stxxl/tags/1.2.1/algo_2sort__file_8cpp-example.html in VS2010. However the file data was not mapped to the vector_type, in fact it deleted the contents of the file after this statement - vector_type v(&f); I tried changing from stxxl::file::RDWR to stxxl::file::RDONLY, this time the file content was not deleted, however still the vector_type variable was empty.Request your support to proceed further. Also, is STXXL used widely in commercial applications?

You are running a code example from STXXL version 1.2.1, which version have you installed on your system?
Most up-to-date version is "Development 1.4" which comes with many improvements, a comprehensive documentation with a lot of short code examples and runs pretty well - check the official STXXL Website under "Downloads and Documentation". Using version 1.4 is highly recommended.
Please check if your problem still exists on the new "Development 1.4" version. The Installation Process has become much easier - read the Installation and Configuration Part of the Documentation at first.
The official webpage provides a (certainly incomplete) list of Publications,Ongoing and Completed Projects using the STXXL successfully - there is no reason why not using it in an commercial environment.
