bit crunching with gbytes and sbytes

[bandito]

hi,<br>
I try to get a piece of code working, that<br>
relies on this functionality:<br>
gbytes(p,u,q,b,s,n)<br>
gbyte (p,u,q,b)<br>
sbytes(p,u,q,b,s,n)<br>
sbyte (p,u,q,b)<br>
<br>
q >= 0 number of bits to be skipped preceeding first byte in p<br>
0 < b < sword byte size<br>
s >= 0 number of bits to be skipped between bytes<br>
n >= 0 number of bytes to be packed/unpacked<br>
<br>
gbytes unpacks n b bit bytes from p into u, starting by skipping<br>
q bits in p, then skipping s bits between bytes.<br>
gbyte unpacks one such byte.<br>
sbytes packs n b bit bytes from u into p, starting by skipping<br>
q bits in p, then skipping s bits between bytes.<br>
sbyte packs one such byte. */<br>
What are these routines called in hpunix, and how<br>
are they loaded, when compiled together with c and fortran code?<br>
Bernd.
