## tableng

tableng — Interrogates a function table for length.

## Description

Interrogates a function table for length.

## Syntax

    ires tableng ifn

    kres tableng kfn

## Initialization

ifn -- Table number to be interrogated

## Performance

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.

## Examples

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

Example 1078. Example of the tableng opcode.

See the sections Real-time Audio and Command Line Flags for more information on using command line flags.

    <CsoundSynthesizer>
    <CsOptions>
    ; Select audio/midi flags here according to platform
    -odac    ;;;realtime audio out
    ;-iadc    ;;;uncomment -iadc if realtime audio input is needed too
    ; For Non-realtime ouput leave only the line below:
    ; -o tableng.wav -W ;;; for file output any platform
    </CsOptions>
    <CsInstruments>

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

    gifn1 ftgen 1, 0, 0, 1, "flute.aiff", 0, 0, 0	;deferred-size table

    instr 1

    isize tableng 1
    print isize
    andx  phasor 1 / (isize / sr)			;play at correct pitch
    asig  tab andx, 1, 1
          outs asig, asig

    endin
    </CsInstruments>
    <CsScore>

    i 1 0 2.3
    e
    </CsScore>
    </CsoundSynthesizer>

Its output should include a line like this:

    instr 1:  isize = 115506.000
