That's probably the wrong question to be asking.
Why do you want to know this?

I want to get the value of SIGRTMIN (the first real-time signal).
The macro SIGRTMIN uses _sysconf which is not available in a Solaris
driver.
The macro _SIGRTMIN which is a constant value but the value is
different depending on the Solaris version.

I have found solutions to my two own questions:

Current O/S version in a Solaris driver:
------------------------------------------------------

#include <sys/utsname.h>
extern struct utsname utsname;
...
int my_func()
{
int os_release;
os_release = utsname.release;

....
}

Value of SIGRTMIN (the first real-time signal) independent of current
O/S version:
--------------------------------------------------------------------------------------------------------------------

#include <sys/sysconfig.h>
extern long sysconfig(int cmd);
...
int my_func()
{
long sigrtmin;
sigrtmin = sysconfig(_CONFIG_SIGRT_MIN); /* Note: don't use
_SC_SIGRT_MIN because we are in a driver */

....
}
