Hi All,

Are there predefined macros to identify Solaris version at runtime?
We need to differentiate betweeb Solaris8 and later versions.

Thanks,
Alona

Macros are usually used when compiling?

If you want to programatically determine what version of the OS
is running, use sysinfo().

#include <sys/systeminfo.h>
#include <stdio.h>

int main(int argc, char **argv, char **envp)
{
char version[100];
sysinfo(SI_RELEASE,&version,sizeof(version));
printf("System Version is: %s\n",&version);
}

Output:
System Version is: 5.10

You can get the kernel patch rev, architecture, 64bit support or not, etc.

Another way is to use uname, which will get some of the same info.
