All macrolibraries
OS API libraries
Calling convention

This is an overview of libraries which can be included to source files of programs written in EuroAssembler.

Names of all macroinstructions from all macrolibraries are listed in alphabetical order on the main EuroAssembler index page.

Although macrolibraries in this directory maclib are licensed for public domain, it's not recommendable to add your own macros, structures, constants to those files, because your update would have been lost whenever a new version of EuroAssembler overwrites them.
Create a new macrolibrary with unoccupied name instead.

The Realm category specifies visibility of included library members in the source.

Realm EUROASM libraries contain only macros and preprocessing %variables, i.e. redefinable resources which are not constrained by PROGRAM..ENDPROGRAM. Their scope begins at the moment of library inclusion, and it ends at the end of source file.
Macrolibraries from this realm may be included inside the PROGRAM block, or only once at the beginning of source file.

If an EUROASM macrolibrary depends on %variables and macros defined in other library, it should ensure from misorder and start with INCLUDE1 OtherLibrary.

Realm PROGRAM libraries contain definitions of constant symbols and structures, which must be unique in a program.
Libraries from this realm should be included inside the PROGRAM block, otherwise the symbols and structures would not be visible for the assembled program.
Order of their inclusion does not matter.

Structures and symbols retrieved from [WindowsSDK]   were classified by their subsystem or functionality and split to several specialized macrolibraries wins*.htm. This should speed up the assembly time, because ordinary programs usually do not need to include all possible functionalities at once.
Look for the constant/structure name with the Search applet on top of this page when you are not sure which macrolibrary hosts the symbol.
Lazy Windows programmer can include all those libraries at once with INCLUDEHEAD1 wins*.htm in its header.

↑ API libraries

This collection provides macros for interaction with the application programming interface of operating system. It also defines homonymous macros for basic functions of the operating systems: standard console input and output (StdInput, StdOutput), retrieving of command-line arguments ( GetArgCount, GetArg), return from the program to OS (TerminateProgram, TerminateStayResident).

Programming interface macros represent an elegant way of interaction with operating system using only one single statement. Otherwise we would have to push or load appropriate registers with argument values in the right order, store caller-save registers, manually arrange stack alignment, call the imported function and finally restore the stack.

↑ Calling convention libraries

This set of libraries is designed to create procedures conform with usual calling conventions (macros Procedure, EndProcedure). Such procedures can be invoked as an OS-function callback, or invoked by 3rd-party programs, if the procedure is exported from a shared library.

Macros Invoke can be used to exploit procedures and functions from OS or from 3rd-party non-OS libraries. Nevertheless, for interaction with OS it's better to use a specialized API macroinstruction.

The Mode category specifies expansion mode of the macro. Most macros from EuroAssembler libraries are
Robust which means that they do not clobber any registers except for those which return the result. This is suitable for programming style where important variables are kept in GPR permanently and they survive invocation of OS API or of other library function. Robust mode macros also allow to pass function arguments in arbitrary registers.

Fast mode macros do not bother with saving and restoring caller-save registers. Programmers cannot rely on values in scratch registers to remain unchanged by OS interaction. They also need to pay attention to not overwrite values in registers designed for argument transport.

Some API invokation macros allow to select Fast or Robust expansion mode with keyword operand Fastmode=.

64bit libraries employ the macro Uses to explicitly specify the list of registers which the invoked procedure should save and restore. The level of robustness then depends on Uses operands.

Calling convention libraries contain homonymous macroinstructions
(Procedure, EndProcedure, Invoke, LocalVar, ClearLocalVar, Uses). Only one such library should be included in a program. Calling convention library can be combined with API library, see the sample projects for examples.
