call by reference => passing large values to a function, requires coping large amounts of data on the stack, this can be time consuming, and it can cause a stack to overflow, which can crash your program and create security volnerabilities. So, when you pass something large than a simple...
either pass by reference a Python string to Fortran subroutine that could modify it and pass it back (modified) to Python or pass a Python string to a Fortran function that could return the modified string into "something" (see beneath) interoperable enough that Python could get ...

In addition to using the return value itself, you can "return" values by defining any number of parameters to use pass-by-reference so that the function can modify or initialize the values of objects that the caller provides. For more information, seeReference-Type Function Arguments. ...
My problem is that NLopt requires a function reference as input and I am not sure how to handle this since its inside a class. If I compile this I get an error like 12345 min_nlopt.cpp: In member function ‘virtual int LAMMPS_NS::MinNLOPT::iterate(int)’: min_nlopt.cpp:68: err...
A memory stream uses data buffers to pass data between your application and CAPI. This is often the simplest type of stream to use. Read buffers are read by CAPI during CAPI_Store... calls and write buffers are written to by CAPI during CAPI_Fetch... calls. The read buffers are managed...
a suitable actual parameter must be specified for every non-optional input parameter. The content of the actual parameter is passed to the input parameter when the call is made. The content of an input parameter for which 'pass by reference' is defined cannot be changed in the function module...
An output parameter that is defined for pass by reference is not initialized when the function module is called. CHANGING parameters are input and output parameters. When the function module is called, a suitable actual parameter must be specified for every non-optional input or output parameter...
Passes fields to the called program using pass by reference.ID id1is used to specify the name of a formal parameter andFIELD f1is used to specify the associated field from the ABAP program. If a formal parameter expects an internal table, the latter is passed in the formFIELD tab[]. ...
A pass by reference can be coded via references or pointers as function parameters. A parameter of a reference type is an alias for an argument. When a function is called, a reference parameter is initialized with the object supplied as an argument. The function can directly manipulate the ar...
