info(D1str)

info -- STREAMS driver and module information

Syntax

   #include <sys/stream.h>
   #include <sys/ddi.h>

   struct streamtab prefixinfo = { . . . };

Description

In DDI versions prior to version 8, every STREAMS driver and module must define a global streamtab(D4str) structure so that the system can identify the entry points and interface parameters.

References

Notices

Hardware constraints

None

Applicability

ddi: 1, 2, 3, 4, 5, 5mp, 6, 6mp, 7, 7mp, 7.1, 7.1mp

Backward compatibility

UnixWare-specific driver data

Forward compatibility

Starting with DDI 8, the streamtab(D4str) structure is available through the drv_str member of the drvinfo(D4) structure, instead of being a global variable.
