These are really nice. One minor comment is that the ::print
usage doesn't take advantage of some of the enhancements to ::print
in Solaris 10. Two tricks:
1. quoting is no longer required for "struct foo"
2. you can print structure members and dereference pointers using
'.', '->', and '[]'. (in particular, putting '[]' at the end
of a chain of things will dereference pointer elements)
Combined, these make:
> ffffffff8126fdc8::print "struct modctl" mod_linkage |
::print "struct modlinkage"
{
ml_rev = 0x1
ml_linkage = [ 0xffffffffc00aaeb0, 0, 0, 0, 0, 0, 0 ]
}
> modldrv1::print "struct modldrv"
{
drv_modops = mod_driverops
drv_linkinfo = 0xffffffff5196e72 "AMD Powernow! 1.15 (ACPICA)"
drv_dev_ops = powernow_dev_ops
}

::print "struct cb_ops" cb_ioctl
cb_ioctl = powernow_ioctl

}

Note that we can't make this shorter, since ml_linkage is typed as "void *".
