Retrieving Version String

The components of sensitivity labels and clearances; and the handling caveats that appear on printer output are specified in a site-specific label_encodings(4) file. Some of the programming interfaces described in this chapter access these specifications in the label_encodings file, and therefore, their outputs vary depending on the label_encodings file in use for a particular site.

This example gets the version string of the label_encodings file accessed in some of the code examples in this chapter, and prints the version string to standard out.

#include <tsol/label.h>

main()
{
	int retval, length = 0;
	char *version = (char *)0;

	retval = labelvers(&version, length);
	if(retval > 0)
		printf("Version string = %s\n", version);
}

The printf statement prints the following:

Version string = TRUSTED SOLARIS MULTI-LABEL SAMPLE VERSION -
    5.5 00/07/19
