NAME

streamadm − 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

sa_version
Version identifier for the streamadm structure.  Used for compatibility reasons. 

sa_flags
A flag indicating the type of STREAMS.  Possible values are

STR_IS_DEVICE
For a STREAMS driver.

STR_IS_MODULE
For a STREAMS module.

sa_name 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. 

sa_ttys 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. 

sa_sync_level
The synchronization level for the module or driver.  This field is relevant on multiprocessors. Some possible values are

SQLVL_GLOBAL
Global synchronization.

SQLVL_FAMILY
Module family synchronization.

SQLVL_MODULE
Module synchronization.

SQLVL_QUEUE_PAIR
Queue pair synchronization.

SQLVL_QUEUE
Single queue synchronization.

sa_sync_info
A pointer to synchronization data.  This field is relevant if sa_sync_level is SQLVL_FAMILY. 

DESCRIPTION

The streamadm structure defines additional configuration information for a STREAMS module or driver.  The OSF/1 configuration procedure uses this structure in addition to the traditional streamtab structure when configuring a STREAMS module or driver.
