GridRPC Call Functions

The four GridRPC call functions may be categorized by a combination of two properties: block- ing behavior and calling sequence. A call may be either blocking (synchronous) or non-blocking (asynchronous) and it may use either a variable number of arguments (like printf) or anargument stack calling sequence. The argument stack calling sequence allows building the list of arguments to the function at runtime through elementary stack operations, such as push and pop.
