This symbol enables a program, such as the runtime linker, to find its own dynamic structure without having yet processed its relocation entries. This method is especially important for the runtime linker, because it must initialize itself without relying on other programs to relocate its memory ...
因为可执行文件依赖于很多动态共享对象(DSO),这个时候,可执行文件对于很多外部符号的引用还处于无效地址的状态,即还没有跟相应的共享对象中的实际位置链接起来,所以在映射完可执行文件之后,操作系统会先启动一个动态链接器(Dynamic Linker)

dlopen接收一C-style字符串,返回一个对dynamic library的handle.如果文件名为NULL,返回到main program的handle。如果filename中包含"/",就会将其理解为一个(相对或者绝对)路径名。否则dynamic linker按照下面的顺序搜索library: 如果calling program的可执行文件包含DT_RPATH tag,并且不包含DT_RUNPATH tag,那么在DT_PPA...
The linker finds all of the required programs, and links them together. The parent maps the program images into the designated addresses thereby completing the linking of the executable application program. In finding the required programs, the linker first checks the image cache to see if the ...
In load-time dynamic linking, an application makes explicit calls to exported DLL functions like local functions. To use load-time dynamic linking, provide a header (.h) file and an import library (.lib) file when you compile and link the application. When you do this, the linker will pr...

When you do this, the linker will provide the system with the information that is required to load the DLL and resolve the exported DLL function locations at load time.Run-time dynamic linkingIn run-time dynamic linking, an application calls either the LoadLibrary function or the LoadLibr...
