How does the history of JPI relate to the notability of Clarion? As the article is currently written, its notability is dubious. Something should be done about the history section - way too long.

I've removed the code examples as they were possible copyright infringements and made an already too-long article even longer. I'm going to delete some of the trivial info. I've tagged this article for its complete lack of references. Kartano ( talk) 22:58, 13 December 2016 (UTC) Unreferenced / What's the POV issue here?

I've restored this article back to the earlier October 2016 version without the advertising.

DLL and have it automatically create the. LIB file for the DLL using the LIBMAKER.EXE utility program that comes with Clarion as one of the example programs. Clarion provides support for three different calling conventions: PASCAL, C, and TopSpeed's Register Based.Ĭreate a Clarion Library. This form of definition reserves space for Struct1 and is equivalent to the C definition:Ī second important prototyping consideration is the procedure/ function calling convention utilized by another language. Struct1 GROUP ! Struct1 is defined as a GROUP The following is an example of C and C++ code data type equivalents.Ī Clarion GROUP is roughly equivalent to a C or C++ struct. For example, the CLARION Language Reference identifies the Clarion data type SREAL as a "four-byte signed floating point". Equivalent data types can be determined by considering the "underlying" machine data type represented by each language data type. A primary consideration is relating equivalent data types in the other language to Clarion. There are several issues to consider when creating equivalent prototypes in Clarion which are dependent upon a DLL's source code language.

For example, if the DLL name is MY.DLL then the module structure would be: The prototypes are placed in a MODULE structure which identifies the name of the DLL's library as the MODULE parameter. Procedures and functions written in a language other than Clarion can still be referenced in a Clarion program by creating an equivalent Clarion prototype. DLL procedures and functions must be in the CLARION program's MAP structure. Reference the Library (.LIB) File in the Project System.

If you have a Windows DLL (not created with Clarion) that you want to use in a CLARION program, then the following steps are required to enable the CLARION program to access the DLL's procedures and functions:Ĭreate Equivalent Clarion Language Prototypes.Ĭreate a Clarion Library (.LIB ) File for the DLL. This Library file entry enables the linker to resolve the procedure and function references in the. Also, Clarion requires a Library (.LIB) file in the Project Tree under Library and Object files. If the source language prototypes are known, then equivalent Clarion prototypes must be created and included in a CLARION program's MAP for all referenced DLL procedures and functions. See the Programmer's Guide article on Multi-Language Programming for more information on this topic. DLLs which have not been created with Clarion if you know the prototypes for the.
