You need to create a method that accepts a pointer to an array, searches that array for a particular element, and returns a pointer to the found element. Solution The FindInArray method, shown here, returns a p
If I have a C function returning a mxArray pointer: mxArray* myCFunction(mxArray* args); Will then Matlab be responsible for deleting the object? What If the function returns a null pointer or the input arguments, is this forbidden, e.g.: mxArray* myCFunction(mxArray* args){ return ...
You need to store the memory for your string somewhere that is stable until the C# code is done or has made a copy of a string. (In general you don't want to return pointers from a C++ function because ownership of the pointer is unclear and it is hard to get the lifetime of th...
To put it more simply, if I want some 1D array, like [1,2,3] in C to be returned as each data corresponds to one timestep in Simulink, how can I do it while avoiding a diagonal matrix returned instead ? If the output data is present as an array, then you may utilize ...

It returns a pointer to a C string, quite a bit different. You could do something like this:interfacefunction foo ()integer(int_ptr_kind()) :: fooend function fooend interfacecharacter(30) fstrpointer (pstr,fstr)pstr = foo()i len= index(fstr,char(0))fstr = fstr(1:ilen-1)!
But such a pointer parameter could also be an input for the function. Thus, it has to be clearly described in the API documentation which parameters are for input and which are for output. For simple, scalar C types the caller can simply pass the pointer to a variable as a function ...

Golang编程语言中的指针是一个变量,用于存储另一个变量的内存地址。我们可以将指针传递给函数,也可以从Golang中的函数返回指针。在C/ c++中,不建议在函数之外返回局部变量的地址,因为它在函数返回后超出了作用域。因此,要在C/ c++中执行从函数返回指针,必须将局部变量定义为静态变量。
