ir tableng ifn kr tableng kfn
Interrogates a function table for length.
ifn – Table number to be interrogated
kfn – Table number to be interrogated
tableng returns the length of the specified table. This will be a power of two number in most circumstances. It will not show whether a table has a guardpoint or not. It seems this information is not available in the table's data structure. If the specified table is not found, then 0 will be returned.
Likely to be useful for setting up code for table manipulation operations, such as tablemix and tablecopy.
As of Csound version 3.52, the name of the opcode itablegpw has been changed to tableng.
