[Octave-bug-tracker] [bug #54111] binary data read using "fread" doesn't recognize any "PRECISION" arg in Windows 10

[Rik]

Update of bug #54111 (project octave):

                  Status:                    None => Invalid                
             Open/Closed:                    Open => Closed

Follow-up Comment #2:

I think Michael is correct in comment #1.  Try 'help fread' and note this
paragraph


The PRECISION argument may also specify a type conversion.  For
example, 'int16=>int32' causes 'fread' to read 16-bit integer
values and return an array of 32-bit integer values.  By default,
'fread' returns a double precision array.  The special form '*TYPE'
is shorthand for 'TYPE=>TYPE'.


Modifying your code to include the type conversion


octave:1> fidw=fopen("test.bin","w");
octave:2> fwrite(fidw,[100],"int8");
octave:3> fclose(fidw);
octave:4> fidr=fopen("test.bin","rb");
octave:5> val=fread(fidr,1,"int8=>int8")
val = 100
octave:6> fclose(fidr);
octave:7> whos val 
Variables in the current scope:

   Attr Name        Size                     Bytes  Class
   ==== ====        ====                     =====  ===== 
        val         1x1                          1  int8

Total is 1 element using 1 byte



Marking as invalid and closing report.
