## getftargs

getftargs — Fill a string variable with the arguments used to create a function table at k-rate.

## Description

Plugin opcode in getftargs.

getftargs writes the arguments used to create a function table to a string variable. getftargs runs both at initialization and performance time.

## Syntax

    Sdst getftargs iftno, ktrig

## Initialization

ifno -- Number of the table whose arguments we want to request.

## Performance

Sdst -- output string variable.

ktrig -- trigger signal, should be valid at i-time. The output string variable is filled at initialization time if ktrig is positive, and at performance time whenever ktrig is both positive and different from the previous value. Use a constant value of 1 to print once at note initialization.

## Examples

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

    ; For Non-realtime ouput leave only the line below:

    sr = 44100
    ksmps = 32
    nchnls = 2
    0dbfs  = 1

    instr 1
    Sargs getftargs 1, 1
    puts Sargs, 1
    endin

Its output should include this line:
