Software LibrariesSoftware Libraries

◦A library is a code file that provides functions and data to other code files

◦A code file that uses a function or data item provided by a library is said to be that library’s client

◦Libraries can be: Linkable (static) Loadable (dynamic)

1 - TNS/E Overview 4

Dynamic LibrariesDynamic Libraries◦A DLL is an industry-standard type of

loadable library that: Provides functions and data needed by

the program and/or other loadable files Allows you to partition your applications

into functional units (DLLs)◦Dynamic

Implicit DLLs (previously System Library) Public DLLs (previously SRLs) Ordinary DLLs

(only one accessible as User Library)

DLL AdvantagesDLL AdvantagesDLLs offer many advantages:

◦Programs can use many DLLs◦Additional libraries can be loaded

after the program starts

◦Different processes can run with different versions of a DLL Even running same program file

Execution ModesExecution Modes◦Interpreted TNS mode — TNS millicode

(Itanium instructions) emulating TNS instructions and TNS data and stack layout on User Data (UD) area and TNS register state

◦Accelerated TNS mode — Itanium instructions executing the equivalent of TNS instruction and TNS data and stack layout on UD area and TNS register state

◦TNS/E mode — Itanium instructions using native architecture and data layout and either the MAIN or PRIV stack area
