volatile tells the compiler that the value of the variable may change at any time, preventing the compiler from optimizing access. 1. Used for hardware registers, signal handlers, or shared variables between threads (but modern C recommends std::atomic). 2. Each access is directly read and write memory instead of cached to registers. 3. It does not provide atomicity or thread safety, and only ensures that the compiler does not optimize read and write. 4. Constantly, the two are sometimes used in combination to represent read-only but externally modifyable variables. 5. It cannot replace mutexes or atomic operations, and excessive use will affect performance.

There are mainly the following methods to obtain stack traces in C: 1. Use backtrace and backtrace_symbols functions on Linux platform. By including obtaining the call stack and printing symbol information, the -rdynamic parameter needs to be added when compiling; 2. Use CaptureStackBackTrace function on Windows platform, and you need to link DbgHelp.lib and rely on PDB file to parse the function name; 3. Use third-party libraries such as GoogleBreakpad or Boost.Stacktrace to cross-platform and simplify stack capture operations; 4. In exception handling, combine the above methods to automatically output stack information in catch blocks

To limit the size of client requests, the maxAllowedContentLength parameter can be modified in web.config, such as setting it to 104857600 (100MB), and synchronizing the maxRequestLength of ASP.NET at the same time; to reasonably set the connection timeout time, it can be modified through the IIS manager or appcmd.exe command, with the default of 120 seconds, and the API scenario is recommended to set it to 30-90 seconds; if the request queue is full, you can increase MaxClientConn and QueueLength, optimize application performance, and enable load balancing to relieve stress.

To call Python code in C, you must first initialize the interpreter, and then you can achieve interaction by executing strings, files, or calling specific functions. 1. Initialize the interpreter with Py_Initialize() and close it with Py_Finalize(); 2. Execute string code or PyRun_SimpleFile with PyRun_SimpleFile; 3. Import modules through PyImport_ImportModule, get the function through PyObject_GetAttrString, construct parameters of Py_BuildValue, call the function and process return

When configuring dynamic compression in IIS, selecting content types reasonably can improve performance. First enable the dynamic compression module, install and configure web.config or IIS manager through the server manager. Secondly, set appropriate content types, such as HTML, CSS, JavaScript, and JSON, text content is suitable for compression, while pictures and videos are not suitable. Finally, pay attention to the impact of client compatibility and performance, monitor CPU load, client support status and small file compression effects, and adjust the configuration based on actual traffic to obtain the best benefits.
