A function-call expression has the value and type of the function's return value. A function can't return an object of array type. If the function's return type is void (that is, the function has been declared never to return a value), the function-call expression also has void type...

being used within C++ code So we see that a C function was successfully called from a C++ code. Also, read this for detailed information onhow to create shared libraries in Linux. 2. Call C++ functions from C In this section we will discuss on how to call C++ functions from C code. ...

CallPrintfText(PrintfText);return0; } 调用函数向其函数中传递void (*callfuct)(void)这是一个void callfuct(void)函数的入口地址,即PC指针可以通过移动到该地址执行void callfuct(void)函数,可以通过类比数组来理解。 实现函数调用中,函数调用了“调用函数”,再在其中进一步调用被“调用函数”。相比于主函数直接...

A function call is an expression that includes the name of the function being called or the value of a function pointer and, optionally, the arguments being passed to the function. Syntax postfix-expression: postfix-expression ( argument-expression-listopt ) argument-expression-list: assign...
