fprintks

fprintks — Similar to printks but prints to a file.

Description

Similar to printks but prints to a file.

Syntax

fprintks "filename", "string", [, kval1] [, kval2] [...]

Initialization

"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.

Performance

kval1, kval2, ... (optional) -- The k-rate values to be printed. These are specified in string with the standard C value specifier (%f, %d, etc.) in the order given.

fprintks is similar to the printks opcode except it outputs to a file and doesn't have a itime parameter. For more information about output formatting, please look at printks's documentation.

Examples

Here is an example of the fprintks opcode. It uses the files fprintks.orc and fprintks.sco.

Example 160. Example of the fprintks opcode.

/* fprintks.orc */
/* Written by Matt Ingalls, edited by Kevin Conder. */
; Initialize the global variables.
sr = 44100
kr = 4410
ksmps = 10
nchnls = 1

; Instrument #1 - a score generator example.
instr 1
  ; K-rate stuff.
  kstart init 0
  kdur linrand 10
  kpitch linrand 8

  ; Printing to to a file called "my.sco".
  fprintks "my.sco", "i1\\t%2.2f\\t%2.2f\\t%2.2f\\n", kstart, kdur, 4+kpitch

  knext linrand 1
  kstart = kstart + knext
endin
/* fprintks.orc */

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

        

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

i1      0.00    3.94    10.26
i1      0.20    3.35    6.22
i1      0.67    3.65    11.33
i1      1.31    1.42    4.13
