Today, when you write a program, you use the Pthread_cond_timedwait function, which is the prototype: int pthread_cond_timedwait (pthread_cond_t *restrict cond, Pthread_ mutex_t *restrict Mutex, const struct TIMESPEC *restrict abstime); The last parameter is the TIMESPEC structure, but the man did not give a specific definition, had to check it himself. The following is the specific steps, but also for everyone to make a reference, while welcome to p

1. How do I differentiate between macro names and macro strings in a macro definition? What should I pay attention to for macros with parameters? In a macro definition, the macro name and macro string are distinguished by spaces. When the compiler is working on a macro definition, first read the string from the first space after "#define" until the next space is

Objective:Almost all applications on a computer use string data as the processing object, however, the hardware structure of the computer we are using today is primarily reflective of the need for numerical computation, so it is much more complex to process string data than to process integers and floating-point numbers. Moreover, in different types of applications, the strings handled have different charac

FeasibilityAfter investigation and analysis, the current airline ticket booking system flow chart is as follows:Feasibility of ③ operationComparing the above two figures, compared with the artificial system, the computer retains the original main work flow, you can see that the computer system is the optimization of artificial systems, operation is not complex, staff in a short time after training can be m

The literal explanation is "divide and conquer", which is to divide a complex problem into two or more identical or similar sub-problems, then divide the problem into smaller sub-problems ... Until the last sub-problem can be solved simply, the solution of t

incomplete.The Problem description should involve the problem itself, rather than a computer-based solution.4. Confirm the problem and solution as much as possibleAll OO systems must be modeled. If there is a good solution to the existing problems, but the real problem is that people cannotTo quickly execute existing solutions, you need to model the existing solutions. That is, manual process automation is all necessary, and yourThe manual process sh

[BLE--HID] usb hid device category definitionBrief Introduction HID devices are human-computer interaction devices. Common devices include the mouse, keyboard, and game handle. Generally, the wired connection is connected to the machine device through a USB connection, which serves as the user input device. In bluetooth technology, access to HID devices is wireless. However, the definition of HID is the sam

I. Definition and creation of functionsfunction is Python The basic program structure provided for maximum reuse of code and minimization of code redundancy, which enables programmers toComplex systems are decomposed into manageable parts. in the Python You can create four types of function: Global functions: definition in templatesLocal functions: nesting in other functionsLambda Functions:

freely on a Web site, stateless and anonymous access can be made, but Web applications are generally not accepted.3.2.1 The definition of ASP applicationsThe above can be considered a reasonable general definition of the term "Web application", but unfortunately, this is not enough when talking about "ASP applications." The answer to what is "Web application" can be subjective, and the answer to what is "A

The difference between a variable's definition and a declarationFirst, the definition of a variable must occur before the variable declaration (extern), the declaration of a variable can have more than one, but the definition of the variable is only one, the declaration of the variable affects the reference and scope of the variable, and the
