fread and 24 bit precision

[Alois Schloegl]

I do have 24bit and 12bit integer data in a binary file and need to load 
this into Octave.
I'm aware that I could use a workaround like the following.
[s,c] = fread(fid,3*nr,'uint8');
s=reshape(s,3,nr);
s(3,s(3,:)>127)=s(3,s(3,:)>127)-256;
s=(2^[0,8,16])*reshape(s,3,nr);

The disadvantage of such a solution are:
(1) the octave code is not very clean, and
(2) degrades the performance

Therefore, I'm asking if somebody is working on a native support of 
24bit data in fread?

cheers,
   Alois
