In the past few days, I have studied the source code of uC/OS II and found that the program design method provided by it can effectively solve the problem of the above title. It is mainly implemented through the # ifdef preprocessing command. Let's talk about the confusion caused by extern! Suppose there are five files: Main. C, hello. C, flow. C, etc. C, include. h. If some global variables are defined in Main. C, as follows: Char obu_channel Char ob

In C ++, the STL container type is used as a function and does not use references, which leads to a decrease in program efficiency. stl containers I recently found a problem with algorithm questions: I implement an algorithm recursively, but in the TreeNode * createTree Function(Vector , Int left, int right) TreeNode * createTree (Vector , Int left, int right), The result always times out, I found some

Currently, client requests for ping service have two interfaces: weblogupdates. Ping and weblogupdates. extendedping, which are compatible with the former. Most Ping service servers support bot

change the current working directory to the root directory. no one wants to unload the root directory. For more information about how to use chdir, see Appendix 1. Of course, in this step, if there are special needs, we can also change the current working directory to another path, such as/tmp. 4. set the file permission mask to 0. This requires that the system call umask be called. See Appendix 3. Each process inherits a file permission mask

ObjectiveC # developed a console program that receives the string[] args parameter by default. If more than one parameter needs to be entered, it can be entered sequentially, but if some parameters are not required, or if some of the parameters need to have spaces such as time "2016-05-18 24:35:00", it is more troublesome to deal with them. Some common command-line tools provide a way to specify parameters, such as: curl C:\users\administrato

It can wrap all outputstreams and provide them with a buffer function to improve the efficiency of the output stream. Similar to bufferedwriter, it also provides two Constructors Public bufferedoutputstream (outputstream out) Public bufferedoutputstream (outputstream out, int size) The function is similar to the bufferedwriter mentioned above.

In Linux, Mtrace is used to check program memory overflow-general Linux technology-Linux programming and kernel information. The following is a detailed description. You may encounter problems such as memory overflow when writing complex programs with many pointers. Debugging is also quite tiring. In fact, there is a tool in Linux that can be used for debugging. This is Mtrace. Mtrace can detect memory allocation and leakage failures. Next, let's take
