INtime <strong>3.1</strong> <strong>Software</strong> Exception handling High-level calls System call SetRtExceptionHandler GetRtExceptionHandlerInfo Description Assigns an exception handler and exception mode or changes the current mode for any of the following: • Current thread exception handler • Current process exception handler • System-wide exception handler The GetRtExceptionHandlerInfo function returns the address and exception-handling mode for any of the following: • Current thread’s exception handler • Current process’ exception handler • System-wide exception handler • System-wide hardware exception handler (trap handler) Interrupts This group provides the system calls required to manage interrupts. Interrupt requests are encoded to indicate their source; the resulting coding is called the interrupt level. This encoded interrupt level is required in a number of the system calls in this group. Macros are provided in the header files for the 15 standard PC interrupt levels, IRQ0_LEVEL to IRQ15_LEVEL. High-level calls System call SetRtInterruptHandler SetRtInterruptHandlerEx ResetRtInterruptHandler EnterRtInterrupt GetRtInterruptLevel SignalRtInterruptThread SignalEndOfRtInterrupt Description Assigns an interrupt handler to the specified interrupt level, and optionally makes the calling thread the interrupt thread for that level. Cancels the assignment of the current interrupt handler to the specified level and disables the level. Allows the interrupt handler to have access to static data belonging to the RT process which owns the handler. This function is called from an interrupt handler. Returns to the calling thread the highest (numerically lowest) level that an interrupt handler has started servicing but has not yet finished. Sends an EOI signal to the interrupt hardware then schedules the interrupt thread associated with the specified level. This function is called from an interrupt handler. Sends an EOI signal to the interrupt hardware. This function is called from an interrupt handler. 116
Appendix A: INtime software system calls System call WaitForRtInterrupt DisableRtInterrupt EnableRtInterrupt Description Used by an interrupt thread to signal its readiness to service an interrupt. It blocks for the given number of milliseconds. Disables the specified interrupt level. It has no effect on other levels. Enables a specific interrupt level which must have an interrupt handler assigned to it. Mailboxes These calls manage various RT kernel mailbox object types. INtime software includes two kinds of RT mailboxes: • Object mailboxes manage RTHANDLES. • Data mailboxes manage short sections of arbitrary data. NTX calls System call ntxCreateRtMailbox ntxDeleteRtMailbox ntxReceiveRtHandle ntxSendRtHandle ntxSendRtData ntxReceiveRtData Description Creates an RT mailbox. Deletes an RT mailbox. Receives RTHANDLES from an object mailbox. Sends RTHANDLES to an object mailbox. Copies arbitrary data to a data mailbox (up to 128 bytes). Copies arbitrary data out of a data mailbox (up to 128 bytes). High-level calls System call CreateRtMailbox DeleteRtMailbox SendRtHandle ReceiveRtHandle SendRtData ReceiveRtData Description Creates a new mailbox and returns an RTHANDLE for the object. The mailbox type is determined by the flags parameter. Deletes the mailbox specified by the RTHANDLE given. Sends an RT object RTHANDLE to a mailbox which has been created to pass RT objects. Receives an RTHANDLE from an object mailbox. Copies arbitrary data to a data mailbox (up to 128 bytes). Copies arbitrary data out of a data mailbox (up to 128 bytes). 117
