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

The database schema definition language DDL (Data Description Language) is the language used to describe the real-world entities to be stored in the database. A database schema contains descriptive definitions for all entities in the database. These definitions include the structure definition, the operation method definition, and so on. The pattern of DDL descr

Class Definition details in C ++ Member variables Each class can have no members or multiple members. The members can be data, functions, or type aliases. A class can contain several public, private, and protected parts. Members defined in the public part can be accessed by all code using this type; Members defined in the private part can be accessed by other class members. Protected can be accessed by the quilt class. Constructor A function that has

variable declarations and variable definitions Variable definitions: Used to allocate storage space for a variable, and to specify an initial value for a variable. In a program, a variable has and has only one definition. Variable declaration: Used to indicate the type and name of a variable to a program. A definition is also a declaration, an extern declaration is not 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

To understand the definition and execution of JavaScript functions, you need to know these important concepts first, and now you can understand them later!the execution environment of the function (Excution context), the active object (call object), scope (scope), scope chain (scope chain). Next, let's take this function as an example to analyze:Steps:1. Set the scope chainWhen you define function A, the JS interpreter willScope Chain (scope chain)Set

Like to read some Open-source project source, always will find that the great God's code always have some short and efficient macro definition, click to see, find obscure, not to mention learning, sometimes understanding is a difficult, but the macro definition itself is not so difficult, But write a good macro of course still need rich experience and technology, then say a macro

In Java, an array is considered an object When you define an array, there are two definitions: int[] A and int a[]; the second is a C + + array-defined method, with the first definition of Java recommendations. The general principle: any object must be initialized before being called. definition of 11-D arrays Defines a one-dimensional array that contains three elements //Method 1, first the new object, an

css| Project This tutorial mainly explains the definition of the style of common tags Li {list-style-image:url (images/disc.gif);} This style definition for Li is to use a picture for a list item instead of a small dot that is displayed. Of course, you can also display other effects, see the following definition in detail: 　　CSS

Let's start with an introduction to creating and managing tables and views

For example, as seen in:The male female head is used in the packaging of the connecting wire. However, a 90-degree angled pin package is used for the Development Board. For example, with:Each pin is defined as:2. Connection of male female head to MAX232When the male head is connected with the MAX2

1 OverviewUsed preprocessing commands starting. For example, include the command # include and macro definition command # define. In the source program, these commands are placed outside the function, and are generally placed before the source file. They are called preprocessing. Preprocessing refers to the work done before the first scanning (lexical scanning and syntax analysis) of compilation. Preprocessing is an important function of C language, w

#defineThe command #define defines an identifier and a string. Each time the identifier is encountered in the source program, it is substituted with a defined string. The ANSI standard defines an identifier as a macro name and replaces the process with a macro substitution. The general form of the command is: #define Identifier string Attention:1. The statement does not have a semicolon. There can be any space between the identifier and the string, which, once started, ends only wi

Definition of structureThe general form of defining a structure is:struct structure name{Member table columns}A member table consists of several members, each of which is an integral part of the structure.A type description must also be made for each member.For example: Copy Code code as follows: struct STU { int num; Char name[20]; int age; } description of struct type variableA struct
