Description

Deletes function table.

Syntax

ftfree ifno, iwhen

Initialization

ifno -- the number of the table to be deleted

iwhen -- if zero the table is deleted at init time; otherwise the table number is registered for being deleted at note deactivation.

	Note
	If the table is deleted at init time it is possible that an earlier opcode that uses the table will fail or crash on a performance cycle. It is the user's responsibility to avoid this error.

Examples

Here is an example of the ftfree opcode. It uses the file ftfree.csd.
