C-Runtime Library: String trim Function
In the past, I always thought that the C Runtime Library does not contain functions such as string trim (in the code left by my predecessor, the big guys always write one by themselves :). In fact, in C runtime, there is a string trim
1. If C # calls the VC's dynamic library, and the DLL uses MFC, the MFC must be statically linked to the DLL.2. C # calls the C + + dynamic Library in three ways: COM components, managed code, unmanaged code.COM components need client registration, if the customer does not h
Because the laboratory image processing algorithms are written under the OpenCV, there is also the navigation algorithm is written in C + +, and then the interface is required to write in C #, so whether it is the socket communication, or call OpenCV DLL module, are designed to C # and C + + data type correspondence, T
The following is how c creates and calls a DLL:

This article attempts to use zeromq to complete a simple network transfer task.
(Tom uses the open-source shared library (C uses zeromq). This article has completed a simple and runable BASIC Program. This article is based on this transformation)
The modified content of Main. C is as follows:

C # calling C + + Dynamic Library considerationsThe recent project needs to call C + + in C #, during which a number of pits were encountered, summarized as follows:1.in const char* corresponds to string or IntPtr in C #2.out Cons
A c Language Runtime Library provides the following functions:
1. Start and exit: including the entry function and other functions on which the entry function depends
2. Standard Functions: these functions are implemented by the C language standard library.
3. I/O: encapsulation and implementation of Io Functions

28 C/C ++ open-source JSON library performance and standard compliance evaluation
There are a lot of C/C ++ JSON libraries in the workshop. It is a difficult choice.

[C/C ++ standard library] _ [elementary] _ [map lookup Function Analysis]
Scenario:
1. map is efficient in searching for objects with non-numeric indexes (which can be a vector for non-repeated numeric indexes), because the implementation of the Red/black tree makes logarithmic time efficient in searching and inserting.
2. map is a very practical data structure.
I want to write a C + + library under Linux to implement some common functions.My first thought was to implement a TCP listener. What functions should the program have?1: Start/Stop monitoring2: Notifies the caller when there is a client connection3: Notifies the caller when disconnected from the client4: Notifies the caller when a message arrives5: Try to avoid the program exit when there is no close socke
Two methods were found in the process to solve the problem: a DLL library created by unmanaged C + + that needs to be called with a static method. This method can not be directly referenced in C # Reference, but to use static call method, the other blog has been described in detail, the only thing to add is that C # fi

Because you need to tell the compiler, C + + in the link to compile C
supports Dom, sax, and DTD verification. The latest version reads and explains some "W3C XML Schema recommendations" (we plan to implement full XML Schema support by the end of 2001 ).
Compiling and linking one of the three most popular libraries to your project is effortless. Most software packages contain detailed descriptions of each platform. Here are some sample installation instructions.
