waste of hard disk space; (two executable files contain ONE.O)Second, when the program loads, the memory is wasted. (Since the ONE.O was loaded two times)Dynamic library, you can solve the above two problems.The same code, the hard disk should be able to exist only one copy, in memory should only exist in order to achieve the savings.This is why, dynamic linking is the time when the program is loaded, only to link. (Because the early link, do not occupy the hard disk space?)That's why, dynamic

file, and also to a target file, that is, there is only one function in a target file, there is no other thing.When you use it, you can pick and choose which target file to link to.For example, your colleague already has these:ONE.C contains the void One () {} functionTWO.C contains the Void () {} functionTHREE.C contains the void three () {} functionWait a minute....... And it also provides a header file called All.h, which contains a declaration of all the functions he wrote.When you use it,

checks that the WAITPID function terminates normally, otherwise it outputs an error message.Test:Note that the program does not recycle child processes in a specific order. The order in which the child processes are reclaimed is the properties of this particular computer. On another system, even once again on the same system, two sub-processes may be recycled in reverse order . The above test results also illustrate this point. This is an example of a non-deterministic (nondeterministic) behavi

inside the JVM.So what internal information can JTI provide? Simply put, the Java debugger can get any information, JTI can be obtained, this is because the Java debugger is based on JTI write.For two examples, the following are the two calling functions opened by JTI:Getobjectsize: Gets the size of the memory that the specified object occupies.Followreferences: Gets all objects that can be accessed from the specified object.In other words, the Java code of the application layer can get the abo

You need to add the following third line to the InitInstance () in the app class: ccommandlineinfo cmdinfo; ParseCommandLine (cmdinfo); // prevent automatic creation of blank subforms // dispatches the command specified on the command line. Returns FALSE if // using/RegServer,/register,/unregserver, or/unregister to start the application. if (!

so-called literal. For example, int num=1,num is a variable box, and 1 is the literal, that is, the thing in the box.In the end, the program output the contents of these three variables, in the console printout of the common statement is System.out.println (), the parentheses inside is to output the content, here is used in the above variable. When you use variables, you need to be aware that they must be declared and initialized before they are used.The simple point of the declaration is the t

Makefile slightly moved, that is, the original beginning of the "Led_on.bin" to "all", eclipse default compilation target is "All", it can be successfully compiled, after compiling will produce led_on.bin,led_on_elf. The former is downloaded to Nandflash, which is used for debugging.can be compiled after the start of configuration debugging, and debugging U-boot The only difference is the name of the specified application, as shown in. The other Debugger commands are the same as those configured

For designing embeddedFor developers of Linux systems, there is a problem that must be taken into account, which is the memory space.We know that embeddedThe storage used by the Linux system is not a floppy disk,Zip disk,CD-ROM,DVD of these well-known large-capacity conventional memory, which is used for exampleRom, CompactFlash,M-systems'sDiskonchip,Sony'sMemoryStick,IBM'sMicrodrive such as small size, with the motherboard on theThe BIOS is similar in size and has very small memory capacity.
