Translate parameters comes in pairs of two words, one descriptor and one value. +

Translate parameters are modified/translated transparently by the kernel. They are used to transfer handles/buffers between the different processes.
Translate parameters are modified/translated transparently by the kernel. They are used to transfer handles/buffers between the different processes.
−The type of parameter is described by the bits 1-3 in the translation descriptor. Parameter types accepted by the kernel are: 0, 1, (2?), 5, 6, 7.
+The number of parameters covered by a descriptor is type-dependent:
+ Type 0:
+ length = (desc >> 26) + 1
+ Type 1, (2?), 5, 6, 7:
+ length = 1
+Type 0 does the following:
+ if desc & 0x30 == 0x20:
+ write process id to value
+ else:
+ translate handle
+ if desc & 0x30 == 0x10:
+ close handle for caller
