1. Download the boost package 2. Enter the root directory for extraction. 3. Run Bootstrap (run Bootstrap. bat on Windows) 4. Compile the library you want to use: Variant = release/debug indicates whether the library you generated has debugging information. Link = static/shared indicates whether the library you generated is a static library or a dynamic library. Runtime-link = static/shared indicates whether your library is linked to a static or dynamic Runtime Library; You can specify the Maste

In the previous section, one of the ways of interprocess communication is the signal generation and capture function in signal communication, this section introduces the signal () function and the SET function group of signal processing functions, and then a section http://blog.csdn.net/mybelief321/article/details/9078

Lienhua342014-11-031 Signal Transfer processThe signal source generates a signal for the target process, which is then determined by the kernel to pass the signal to the target process. From the signal generation to the flow to the target process, flowchart 1 shows thatFigur

A signal (signal) is a software interrupt that provides a way to handle asynchronous events and is the only asynchronous communication between processes. In a Linux system, the subsequent signaling mechanism is extended according to the POSIX standard, which can be used to inform not only what happened to a program, but also the process of passing data to it.First, the source of the signalThe source of the

1. sigaction () # Include Int sigaction (int signum, const struct sigaction * act, struct sigaction * oldact )); The sigaction function is used to change the behavior of a process after receiving a specific signal. The first parameter of this function is the signal value, which can be any specific valid signal Except SIGKILL and SIGSTOP (define your own processi

The second parameter of the signal installation function sigaction (int signum, const struct sigaction * Act, struct sigaction * oldact) is a pointer to the sigaction structure (the struct name is the same as the function name, do not confuse it ). In the sigaction structure instance, it specifies the processing of specific signals, the information transmitted by signals, and which functions should be shielded during the execution of

I. Signal Set and related operation functions A signal set is defined as a data type: Typedef struct { Unsigned long sig [_ NSIG_WORDS]; } Sigset_t A signal set is used to describe the set of signals. Each signal occupies one (64-bit ). All signals supported by Linux can appear in the

Signal () function to describe Linux functions in detail A signal (signal) is a interprocess communication mechanism that provides an application with an asynchronous software interrupt that gives the application the opportunity to accept commands (i.e., signals) sent by other program live terminals. After the application receives a

A signal is a software interrupt, an asynchronous communication method that handles an asynchronous event. For example, we run the program in the terminal, by pressing the keyboard "CTRL + C", you can send a SIGINT interrupt signal to stop the program to run.There are 3 ways to handle the signal:1. Ignoring this signal

Baseband signalSource (information source, also known as the terminal) emitted by the non-modulated (for spectral removal and transformation) of the original electrical signal, characterized by a low frequency, the signal spectrum from the zero frequency near the beginning, with a low-pass form. According to the characteristics of the original signal, baseband

Signal ClassificationUnreliable signalThe Linux signaling mechanism is basically inherited from Unix systems. The signaling mechanism in the early Unix system was relatively simple and primitive, and later exposed some problems in practice, and its main problems were:1. Each time the process processes the signal, the response to the signal is set to the default a

The signal module in the Python standard library is further studied based on the learning basis of the Python learning note-the--linux signal basis for multi-process communication.Although signal is a module in Python, it is primarily for UNIX platforms (such as the Linux,mac OS), and the Windows kernel has insufficient support for signaling mechanisms, so Python

The signal is associated with a certain process. In other words, a process can determine which signals are handled in the process. For example, a process can ignore some signals and handle only some other signals, and a process can also choose how to handle the signal. In short, these are always associated with a particular process. Therefore, the first to establish its

Signal signal is a mechanism for sending signals between Python processes, and the principle is that the operating system controls the process and is a program interruptOnce a process receives a signal, it interrupts the original program execution process to process the signal.So what's the use of singanl?Application of Siganl : 1. Fault location technology ( The

1. What is interruption? 1. Basic concepts of Interruption Interruptions refer to any unusual or unexpected emergency handling event in the system during the execution of a computer, this allows the CPU to temporarily interrupt the program being executed and switch to the corresponding event processing program. After the process is completed, the system returns the process of executing the new process that was originally interrupted or scheduled. An event that causes an interruption is called an
