streamadm(4)streamadm(4)NAMEstreamadm - Defines configuration information about a STREAMS module or
driver
SYNOPSIS
#include <sys/stream.h>
struct streamadm(
uint sa_version,
uint sa_flags,
char sa_name [FMNAMESZ+1],
caddr_t sa_ttys,
uint sa_sync_level,
caddr_t sa_sync_info );
PARAMETERS
Version identifier for the streamadm structure. Used for compatibility
reasons. A flag indicating the type of STREAMS. Possible values are:
For a STREAMS driver. For a STREAMS module. The unique name of the
module or driver. Modules and drivers share a common name space. The
maximum length for a name is set by FMNAMESZ. A pointer to the ttys()
routine that will be used by the module or driver. When the module or
driver is added via strmod_add(), this pointer will be placed in the
d_ttys field in the cdevsw structure. If the driver is not a tty
driver, this field is set to NULL. The synchronization level for the
module or driver. This field is relevant on multiprocessors. The pos‐
sible values are: The default, global level synchronization. Global
level synchronization. Arbitrary level synchronization. Module level
synchronization. Queue pair level synchronization. Queue level syn‐
chronization. A pointer to synchronization data. This field is rele‐
vant if sa_sync_level is SQLVL_ELSEWHERE.
DESCRIPTION
The streamadm structure defines additional configuration information
for a STREAMS module or driver. The operating system configuration
procedure uses this structure in addition to the traditional streamtab
structure when configuring a STREAMS module or driver.
The Network Programmer's Guide contains additional information about
the synchronization levels for the module or driver.
