We will see how the function func() can be called from a C code. The first step for this is to change the declaration/definition of this function by introducing the notation extern “C”. #include <iostream> extern "C" void func(void) { std::cout<<"\n This is a C++ code\n"; ...

Use these functions when you want to pass function arguments from C++ to MATLAB and to return the result of the function execution to C++. These member functions work like the MATLAB feval function. To call a MATLAB function: Pass the function name as a matlab::engine::String. Define the...

function callFunc(address addr, bytes data) public { addr.delegatecall(data); } 这将引起任意 public 函数调用的问题:合约中的 delegatecall 的调用地址和调用的字符序列都由用户传入,那么完全可以调用任意地址的函数。 除此之外,由于 delegatecall 的执行环境为调用者环境,当调用者和被调用者有相同变量时,如果...
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...
在ABAP 帮助文档里,将这种通过 CALL 关键字进行的函数调用,标记为 System Function Call - 系统函数调用,只能由 SAP 内部使用,不建议用于应用开发。 CALL 后跟的系统函数名称,需要在 SAP Kernel 源文件 sapctab.h 里声明,并且修改此类系统函数,需要重新编译和链接 ABAP Kernel. SAP 社区上有一篇文章,作者为 ABAP...
