Returning array (pointer) of 2D array in C, Returning array (pointer) of 2D array in C. A function dynamically creates an int array whose elements are predetermined to be int [2]. Is there any way to have a function assign values to that array and then return it to the caller. The ...
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 ...
Returning a pointer to a local variable, which goes out of scope once the function returns, results in undefined behavior when dereferenced. It should be noted that initially, you will encounter compilation errors due to the absence of a pointer return inreturn *key(which returns the value poin...

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 the...

For simple, scalar C types the caller can simply pass the pointer to a variable as a function argument. For the function implementation all the information to interpret the pointer is specified because of the specified pointer type. To return data with complex types, like arrays, either a Call...
