Singleton. Windows. Pthread. Map. C++ Reference [C++ Reference] How to call linux commands in c++ program. MySQL++ MySQL++ is a C++ wrapper for MySQL’s C API. It is built around the same principles as the Standard C++ Library, to make dealing with the database as easy as dealing with STL containers. In addition, MySQL++ provides facilities that let you avoid the most repetitive sorts of SQL within your own code, providing native C++ interfaces for these common tasks.

In most systems, it is usually directed by default to the keyboard. stdin can be used as an argument for any function that expects an input stream (FILE*) as one of its parameters, like fgets or fscanf. Although it is commonly assumed that the source of data for stdin is going to be a keyboard, this may not be the case even in regular console systems, since stdin can generally be redirected on most operating systems at the time of invoking the application. For example, many systems, among them DOS/Windows and most UNIX shells, support the following command syntax: myapplication < example.txt to use the content of the file example.txt as the primary source of data for myapplication instead of the console keyboard.
It is also possible to redirect stdin to some other source of data from within a program by using the freopen function. If stdin is known to not refer to an interactive device, the stream is fully buffered. Stdout. The standard output stream is the default destination of output for applications. In most systems, it is usually directed by default to the text console (generally, on the screen). stdout can be used as an argument for any function that takes an argument of type FILE* expecting an output stream, like fputs or fprintf. Although it is commonly assumed that the default destination for stdout is going to be the screen, this may not be the case even in regular console systems, since stdout can generally be redirected on most operating systems at the time of invoking the application.
For example, many systems, among them DOS/Windows and most UNIX shells, support the following command syntax: myapplication > example.txt to redirect the output of myapplication to the file example.txt instead of the console. It is also possible to redirect stdout to some other source of data from within a program using the freopen function. System. Function int system (const char* command); Execute system command Invokes the command processor to execute a . If is a null pointer, the function only checks whether a command processor is available through this function, without invoking any command. The effects of invoking a command depend on the system and library implementation, and may cause a program to behave in a non-standard manner or to terminate.
Parameters command C-string containing the system command to be executed. Return Value If is a null pointer, the function returns a non-zero value in case a command processor is available and a zero value if it is not. If is not a null pointer, the value returned depends on the system and library implementations, but it is generally expected to be the status code returned by the called command, if supported. Example Data races The function accesses the array pointed by . Exceptions (C++) No-throw guarantee: this function does not throw exceptions. See also exit Terminate calling process (function )
