Notational Conventions

The code and syntax used in this document for function and variable declarations are written in the ANSI C style. However, versions of Intel IPP for different processors or operating systems may, of necessity, vary slightly.
Optimization Notice
Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
Notice revision #20110804
In this document, notational conventions include:
  • Fonts used for distinction between the text and the code
  • Naming conventions for different items.

Font Conventions

The following font conventions are used throughout this document:
This type style
Mixed with the uppercase in function names, code examples, and call statements, for example,
This type style
Parameters in function prototype parameters and parameters description, for example,

Naming Conventions

The naming conventions for different items are the same as used by the Intel IPP software.
  • All names of the functions used for cryptographic operations have the
    prefix. In code examples, you can distinguish the Intel IPP interface functions from the application functions by this prefix.
    In this document, each function is introduced by its short name (without the
    prefix and descriptors) and a brief description of its purpose.
    prefix in function names is always used in code examples and function prototypes. In the text, this prefix is omitted when referring to the function group.
  • Each new part of a function name starts with an uppercase character, without underscore, for example,
