[in] The function table entries. |
Remarks
This function declares a function table as a set of function bodies that have been declared earlier.
This is like a C++ vtable except there is an entry per call site for an interface instead of per method.
There is no limit to how many function bodies can be listed in a function table.
It is valid for a given function body fb# to be referenced multiple times in one or more function tables, as a way of sharing common code.
