## ftfree

ftfree — Deletes function table.

## 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.

Example 377. Example of the ftfree opcode.
