fprints — Similar to prints but prints to a file.


Similar to prints but prints to a file.


fprints "filename", "string" [, ival1] [, ival2] [...]


"filename" -- name of the output file.

"string" -- the text string to be printed. Can be up to 8192 characters and must be in double quotes.

ival1, ival2, ... (optional) -- The i-rate values to be printed. These are specified in string with the standard C value specifier (%f, %d, etc.) in the order given.


fprints is similar to the prints opcode except it outputs to a file. For more information about output formatting, please look at printks's documentation.


Here is an example of the fprints opcode. It uses the file fprints.csd. Note that the example must be run from a directory for which the user has write access.

Example 349. Example of the fprints opcode.

; Instrument #1 - a score generator example.
instr 1
  ; Print to the file "my.sco".
  fprints "my.sco", "%!Generated score by ma++\\n \\n"


/* Written by Matt Ingalls, edited by Kevin Conder. */
; Play Instrument #1.
i 1 0 0.001


This example will generate a file called my.sco. It should contain a line like this:

;Generated score by ma++
