  18 .Sh NAME
  19 .Nm qinit
  20 .Nd STREAMS queue processing procedures structure
  21 .Sh SYNOPSIS
  22 .In sys/stream.h
  23 .Sh INTERFACE LEVEL
  24 .Sy Architecture independent level 1 (DDI/DKI)
  25 .Sh DESCRIPTION
  26 The
  27 .Nm
  28 structure contains pointers to processing procedures for a
  29 .Sy QUEUE .
  30 The
  31 .Sy streamtab
  32 structure for the module or driver contains
  33 pointers to one
  34 .Xr queue 9S
  35 structure for both upstream and downstream processing.
  36 .Sh STRUCTURE MEMBERS
  37 The
  38 .Nm
  39 structure includes the following members:
  40 .Bd -literal -offset indent
