TD> This is a fallacy. For portability across compilers, the VIO subsystem is the *BEST* idea, not an afterthought as you seem to imply. The reason for this is that the VIO subsystem is part of the system API, and thus is available across all compilers, and all languages (that support calling the system API directly). I don't know what you are thinking of when you suggest looking at the generated code for a call to a VIO function. That's hardly going to be much help, since that is just a (thunked) function call. Looking at code to push parameters onto the stack is hardly going to tell you what the function being called does. Watcom C++ 10.5a users have the VIO API documented in the on-line reference (\WATCOM\BINP\HELP\PRCP.INF), along with the rest of the system API. Users of other C++ compilers for OS/2 have to obtain the 1.3 Toolkit (where VIO is documented) separately if they want documentation, but they nevertheless can *all* call the VIO subsystem without problem. And to round off, you may care to note that the VIO API is also available for DOS using either the libraries in the 1.3 Toolkit, or the libraries in FAMAPI.ARJ (which is a port of the 16-bit Family API for OS/2 1.x to DOS, complete with full source, that is available on quality FIDONET files sites worldwide). > JdeBP < ___ X MegaMail 2.10 #0: --- Maximus/2 3.01* Origin: DoNoR/2,Woking UK (44-1483-725167) (2:440/4) SEEN-BY: 50/99 270/101 620/243 711/401 409 410 413 430 808 809 934 955 SEEN-BY: 712/407 515 517 628 713/888 800/1 7877/2809 @PATH: 440/4 141/209 270/101 712/515 711/808 809 934 |
