This article mainly introduces the tutorial of calling the dynamic link library produced by CC ++ in PHP. It also briefly mentions how to create a dynamic link library under the gcc compiler, for more information, see php, which is faster. However, for more advanced developers, there is no doubt that you can write c code by yourself and compile it into a dynamic

The standard C library is the same! Everyone must have done in Windows file programming, under Linux is the same function name, parameters are the Same. There was a doubt, because we knew very wellIts nature is not the same, because it is two operating systems ah! however, because the C standard

The first type of library we will create is the dynamic link library (DLL ). Using DLL is an excellent way to reuse code. You don't have to re-implement the same routine in every program you create, but you just need to write these routines once and then reference them from the application that requires this function.This drill covers the following:

Q: What is the relationship between C library and system APIs?
A: for example, a simple example:
It can be seen that part of the C library uses system APIs to implement its own functions (such as file operations), and the other part does not directly rely on system APIs to implement functions (such as s

C ++ string formatting Library: CPPFormatLibrary, C Language
This was written a long time ago. I summarized it last year and extracted it separately. As an open-source library, it was put on GitHub. However, CPPFormat and other names have already been noticed, as a result, we registered the CPPFormatLibrary, FL for sho
Just bored fiddling with a bit of Baidu's speech recognition Restapi, see the speech recognition sample is written in C + +, a total of three components, LIBCURL.A, Libjson.a, Base64.cpp, at compile time Json::reader undefined reference error. Think of using C to rewrite this example. Restapi is called by first using Skey to obtain tokens, and then the audio (for example: TEST.PCM) by BASE64 encoded into a
