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
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 possible values are: The default, global level synchronization. Global level synchronization. Arbitrary level synchronization. Mod-
ule level synchronization. Queue pair level synchronization. Queue level synchronization. A pointer to synchronization data. This field
is relevant 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.
