To create a class that contains functions capable of throwing exceptions, I plan to catch any exceptions that may arise. I have derived my_exception from the standard exception class and have coded the what() function to retrieve a string from a private string variable. It may be more benefi...
We have included two header files here, and these are “stdio. h” and “string.h” because we have to utilize the functions of both header files. After this, we inserted the “int main()” function, and then we initialized a string with the name “my_str,” and we didn’t add a...
Theformatattribute allows you to identify your own functions which take format strings as arguments, so that GCC can check the calls to these functions for errors. The compiler always (unless -ffreestanding or -fno-builtin is used) checks formats for the standard library functionsprintf,fprintf,...

Windows API functions that contain strings actually exist in two formats: ANSI and Unicode. In the Windows header files, therefore, you'll get both ANSI and Unicode versions of each function that contains a string. For example, following are the two C-language descriptions for the SetWindow...
If you want to use a class in multiple files, you should put the class definition in a header file and define the class methods in a corresponding source file. (You an also useinline functionsfor the methods.) If you want to use a variable in multiple files, you should put the declara...
Here's an example of my code in C: Copy // In DLL's header (.h) file: GetParam(short param_id, void* param); // In my program: unsigned short width; unsigned long exp_time; char cam_name[50]; GetParam(PARAM_WIDTH,(void*)&width); GetParam(PARAM_TIME, (void*)&exp_time);...
(TS). The TS is a packetized data stream, with fixed length packets, including a header. The individual elements of a program, audio and video, are each carried within packets having a unique packet identification (PID). To enable a receiver device to locate the different elements of a ...
If your config object needs to contain private data or virtual functions, it becomes a non-aggregate type. In this case, you must use the following using declaration to inherit figcone::Config's constructors: using Config::Config; struct PhotoViewerCfg : public figcone::Config { using ...
