Easy. Write a C program that #includes <unistd.h> (that is, it gets the
definitions the standard C way) and outputs whatever syntax you prefer,
like for exampel so:
#include <unistd.h>
#include <stdio.h>
main()
{
printf("_SC_OPEN_MAX = %d\n", (int)_SC_OPEN_MAX);
}
If you want to get at standardized constant definitions, that is a very
portable way to do it. It's a lot easier to get right than going through
the include files yourself.
