Reference library-a library package and a library control with custom Properties
Generally, when you customize a control Panel and the control has custom attributes (for example, panel: closedHandle = "@ drawable/foot_bar_right "), the reference address for this control needs to be defined in xml (for example: xmlns: panel = "http://schemas.android.com/apk/com.ex
Input/output boost. Assign
The assign helps to store the values of a sequence into the container. It provides a simple value assignment method by reloading the comma and parentheses operators (operators used for function calls. This library is particularly useful not only for Prototyping-style code, but also for its features, because the code generated by using this library is very readable. You can also

The iostream library not only supports input and output from terminal devices, but also file input and output. File-related input and output class declarations are included in the fstream header file. There are three classes responsible for file input and output.
1) ifstream class: Derived from istream class.2) ofstream class: Derived from ostream class.3) fstream class: Derived from iostream class.
Because the input and output of files are differ

Currently, the common platform written by client/server side requires plug-ins. Each plug-in is hosted in a dynamic library. In Symbian, dynamic calling is not very convenient, now let's summarize the loading methods of various types of libraries.

Math and numerics boost. Integer
This library provides a series of functions for the integer type, such as the maximum value and minimum value constant at the time of compilation [3]. The appropriate size type is given based on the required number of digits, static computing base on 2 logarithm and other functions. It also includes some Type Definitions (typedefs) of the standard header file
The authors of integer are beman Dawes and daryle Walker.
Dynamic Link Library is a common software component technology that provides basic services in a variety of operating systems. For example, the Win32 kernel is composed of three DLL files. This technology is also implemented in the Linux operating system, that is, the standard ojbect object of Linux, and the corresponding file extension is. So.
The following is a simple example to introduce Linux Standard objects.

Open-source pure C log function library ilog3 Quick Start (8. If you prefer simple log function library than log function library)
Many netizens insisted that simple log functions should be used in the project, but they do not like log function libraries. I have no choice but to argue with them over and over again. I also like short and brisk log function libra
A number of open-source projects have also been put on GitHub over the past few years. But because of their own too lazy to promote lazy maintenance lazy to write documents and demo, so most people . but recently intend to make a good toss them. Hope to be a little bit better . toss the purpose is not for what direct interest . just hope if one day I die can give the world to leave something (I like you, also by this sentence disgusting to ...) ================================ the following ite
function symbol is the same as the function declaration. When the client uses the extern "C" method, the client also uses the original function name symbol when compiling the link.It is shown that the C ++ class and member functions cannot be exported due to the C compilation link method.In addition, if we add a standard call convention to the function declaration: DLL1_API int _ stdcall add (int a, int B); (Note that _ stdcall must be added to the function definition ). Then, use depends to vi

//
int csample::substract (int a,int b)

return a-b;
//}
Then use depends to view:
The exported function symbol name is the same as the function declaration. Because the client is used, the import is also used in the extern "C" way, so the client when compiling the link, also uses the function original name symbol.
shows that a C + + class and member function export cannot be used in this way, because of the way in which it is compiled with the method of compiling

The process of learning a language to application programming can be divided into three steps: 1. Learning the syntax, standard library, and idea of a language; 2. Learning the APIs of relevant operating systems (applications)ProgramProgramming Interface); 3. Use the learning class library. After some experience, the three can alternate and deepen each other. In addition, we need to learn some ba
