If you examine the library header files, you will notice some unusual annotations such as __in_z and __out_ecount_part. These are examples of Microsoft's standard source code annotation language (SAL), which provides a set of annotations to describe how a function uses its parameters鈥攖he assumptions it makes about them, and the guarantees it makes upon finishing. The header file <sal.h> defines the annotations.
