System calls
Each RT kernel object has an associated set of system calls: programmatic interfaces
you use to manipulate objects or control the computer’s actions. System calls for one
object type cannot manipulate objects of another type. This protects objects from
inappropriate actions or changes.
Most system calls have parameters, such as values and names, that you can set to tailor
the call’s performance. High-level system calls validate these parameters; a condition
code returned by the call indicates whether or not the call completed successfully.
Invalid parameter usage, such as trying to manipulate an object of the wrong type, or
trying to read or write memory to which you have no access, results in the return of a
‘call failed’ condition code. You can use another system call (GetLastRtError) to
determine the failure’s exact cause.
Examples of tasks you can perform with system calls include:
Function
Create a new mailbox
Set a thread’s priority
Send a handle to an object mailbox
System call
CreateRtMailbox
SetRtThreadPriority
SendRtHandle
Note
For an overview of INtime software’s system calls, see Appendix A, INtime software system calls.
For detailed information, including syntax and parameter values, see Help.
Real time shared libraries
You can build libraries that can be shared by one or more real-time applications. These
Real time shared libraries (RSLs), function essentially like their Windows DLL
counterparts.
An INtime Wizard is provided that integrates with Microsoft Visual Studio to allow
you to easily create an RSL. It produces the framework for an RSL, and sets up the
various Visual Studio settings to generate an RSL that the INtime loader can manage.
For detailed information on creating an RSL, see INtime Help.
