dcl_function_table (sm5 - asm)

  • Article

Declare a function table.

dcl_function_table ft# = {fb#, fb#, ...}
Item Description
ft
 [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.
