getcfg
getcfg — Return Csound settings.
Initialization
iopt -- The parameter to be returned, can be one of:
-
1: the maximum length of string variables in characters; this is at least the value of the -+max_str_len command line option - 1.
![[Note]](images/note.png)
Note In Csound6 there is no maximum string length so the returned value is meaningless -
2: the input sound file name (-i), or empty if there is no input file
-
3: the output sound file name (-o), or empty if there is no output file
-
4: return "1" if real time audio input or output is being used, and "0" otherwise
-
5: return "1" if running in beat mode (-t command line option), and "0" otherwise
-
6: the host operating system name
-
7: return "1" if a callback function for the chnrecv and chnsend opcodes has been set, and "0" otherwise (which means these opcodes do nothing)

The output should include lines like these:
------------------------------
Max string len : 255
Input file name (-i) : adc
Output file name (-o) : dac
RTaudio (-odac) : 1
Beat mode (-t)? : 0
Host Op. Sys. : Linux
Callback ? : 0
