STLport is a multiplatform C++ Standard Library implementation. It is a free, open-source product, featuring the following:

• Standard (ISO/IEC 14882) compliance;
• Advanced techniques and optimizations for maximum efficiency;
• Exception safety and thread safety;
• Important extensions---hash tables, singly-linked list, rope;
• Power debug mode---run time check of the correctness of iterators and containers usage.

STLport works on any platform possible and proves itself as a seamless drop-in for modern production environments. Not only that---it also offers important functionality not provided by any other standard library vendor:

• Debug mode: "Safe iterators" and preconditions with rigorous runtime validity checking;
• Immediately reports STL bugs undetectable otherwise;
• Wide range of configuration knobs to fit particular requirements of your project, including use in embedded systems, such as vxWorks or Windows CE.
