  2. Signal (IPC) - Wikipedia

    en.wikipedia.org/wiki/Signal_(IPC)

    In particular, the POSIX specification and the Linux man page signal (7) require that all system functions directly or indirectly called from a signal function are async-signal safe. [6] [7] The signal-safety(7) man page gives a list of such async-signal safe system functions (practically the system calls), otherwise it is an undefined behavior ...

  3. INT 16H - Wikipedia

    en.wikipedia.org/wiki/INT_16H

    The standard encoding of the keyboard that offers the INT 16 h is a US keyboard. To adapt the coding of the INT 16h to another type of keyboard (for example, an international keyboard), the code must analyze the scan-code of the key pressed, and then perform suitable interpreting.

  4. Thread safety - Wikipedia

    en.wikipedia.org/wiki/Thread_safety

    Thread safe, MT-safe: Use a mutex for every single resource to guarantee the thread to be free of race conditions when those resources are accessed by multiple threads simultaneously. Thread safety guarantees usually also include design steps to prevent or limit the risk of different forms of deadlocks , as well as optimizations to maximize ...

  5. Sleep (system call) - Wikipedia

    en.wikipedia.org/wiki/Sleep_(system_call)

    The sleep() function call can be repeatedly called for short periods of time to slow the execution of a running program or code. Throttling code in this manner provides a coarse mechanism for mitigating the effects of overheating hardware [7] or easing timing issues for legacy programs. The downside to cycling sleep and running states rather ...

  6. Interrupt - Wikipedia

    en.wikipedia.org/wiki/Interrupt

    A hardware interrupt is a condition related to the state of the hardware that may be signaled by an external hardware device, e.g., an interrupt request (IRQ) line on a PC, or detected by devices embedded in processor logic (e.g., the CPU timer in IBM System/370), to communicate that the device needs attention from the operating system (OS) [7] or, if there is no OS, from the bare metal ...

  8. Beginthread - Wikipedia

    en.wikipedia.org/wiki/Beginthread

    Thread execution starts at the beginning of the function func. To terminate the thread correctly, func must call _endthread or end with "return 0", freeing memory allocated by the run time library to support the thread.

  9. Coroutine - Wikipedia

    en.wikipedia.org/wiki/Coroutine

    Threads provide facilities for managing the real-time cooperative interaction of simultaneously executing pieces of code. Threads are widely available in environments that support C (and are supported natively in many other modern languages), are familiar to many programmers, and are usually well-implemented, well-documented and well-supported.
