Send Interrupt Signal To Blender. PPT Lecture 09 Interrupts & 8259 PowerPoint Presentation, free This is called sending the EOI (End Of Interrupt) signal However, commands only give response if they are programmed to recognize those signals
Blender can't handle very low signals, how to approach? Materials and from blenderartists.org
It is not necessary to send signal/interrupt to control execution (start/pause) of Program2, we can think other way to restrict to run program2, may be by using cpulimit. Particularly useful signals include: SIGHUP (1) - Hangup detected on controlling terminal or death of controlling process

Particularly useful signals include: SIGHUP (1) - Hangup detected on controlling terminal or death of controlling process The EOI can be sent at any point inside the interrupt handler, since even if the local APIC tries to send another interrupt, the cpu won't serve it until the interrupts flag is cleared If you're on windows, signal.CTRL_C_EVENT should also work, but try SIGINT first, as that would also work undex Unix (Linux/OSX) Reply reply
What Is Nested Vector Interrupt Control (NVIC)?, 49 OFF. Signal Handling • UNIX operating systems allow user processes to register for and handle signals • Provides exceptional control flow mechanism for user processes • User program registers a signal handler via a system call • Example: typedef void (*sig_t)(int); • sig_tis a function-pointer to a function that takes an int argument and returns void sig_t signal(int sig, sig_t func); SIGTSTP signal pauses the process; SIGCONT signal continues the paused process; SIGINT signal terminates the process
