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...
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. ...

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 ...
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. ...
Receive all the parameters by value, not by reference. Use parameter types that are compatible with types specified in the SQL Server function. If the return data type of the CLR function specifies a table type (RETURNS TABLE), the return data type of the method in <method_specifier> should...
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...
Hello, I'm using a recursive function to get an array of ID from a database passing the array by reference. I need this structure for the function because the database structure is like a tree and there is no limit of level. Here is the code : ___
