Loading a STREAMS Module at Kernel

To load a STREAMS module at kernel, first become root:

system% su
Password:
 system#

To determine whether you are running a 64-bit Solaris or 32-bit Solaris system, use the isainfo(1)utility as follows:

system# isainfo -v
	64-bit sparcv9 applications
	32-bit sparc applications
	 system#

If the command returns this information, you are running the 64-bit Solaris system. If you are running the 32-bit Solaris system, the utility shows the following:

system# isainfo -v
	32-bit sparc applications
	 system#

Use modinfo(1M) to be certain that your system has not already loaded the STREAMS module:

system# modinfo | grep u8lat1  modulename
system#

If the STREAMS module, such as u8lat1, is already installed, the output looks as follows:

system# modinfo | grep u8lat1
89 ff798000  4b13  18   1  u8lat1 (UTF-8 <--> ISO 8859-1 module)
system#

If the module is already installed, you don't need to load it. However, if the module has not yet been loaded, use modload(1M) as follows:

system# modload /usr/kernel/strmod/u8lat1 modulename

This loads the 32-bit u8lat1 STREAMS module at the kernel so you can push it onto a Stream. If you are running the 64-bit Solaris product, use modload(1M) as follows:

system# modload /usr/kernel/strmod/sparcv9/u8lat1

The STREAMS module is loaded at the kernel and you can now push it onto a Stream.

To unload a module from the kernel, usemodunload(1M), as shown below. In this example, the u8lat1 module is being unloaded.

system# modinfo | grep u8lat1
89 ff798000  4b13  18   1  u8lat1 (UTF-8 <--> ISO 8859-1 module)
system# modunload -i 89
