It's not a keyword. In some old C compilers, it was a union meant for
use with certain x86 interrupt routines, for accessing registers.
how it can be used?

Don't.

It is not, and never was, a keyword. It is a union commonly #defined in C
compilers until Microsoft got their act together.

It occurs to me that that response was brusque and not terribly helpful. I
think what you found was a list of what *I* would call "reserved words",
such lists look an awful lot like a list of keywords. So I took a looked at
an old Turboc C++ manual and they have a list of "All Turbo C++ keywords",
including such gems as 'pascal' and several others. I don't think they
should have done that, and it may well be a pervasive thing. I have very
little interest in language lawyering but Stroustrup has a list of keywords
(in his book), and he was there first and is thus entitled to stake a claim
on the usage of the word.

In any event, if someone on this newsgroups mentions keywords they mean the
bona fide listings such as the one in Stroustrp or K&R.
