-/* Display Power Management System (DPMS.)
-
- On XFree86 systems, "man xset" reports:
-
- -dpms The -dpms option disables DPMS (Energy Star) features.
- +dpms The +dpms option enables DPMS (Energy Star) features.
-
- dpms flags...
- The dpms option allows the DPMS (Energy Star)
- parameters to be set. The option can take up to three
- numerical values, or the `force' flag followed by a
- DPMS state. The `force' flags forces the server to
- immediately switch to the DPMS state specified. The
- DPMS state can be one of `standby', `suspend', or
- `off'. When numerical values are given, they set the
- inactivity period before the three modes are activated.
- The first value given is for the `standby' mode, the
- second is for the `suspend' mode, and the third is for
- the `off' mode. Setting these values implicitly
- enables the DPMS features. A value of zero disables a
- particular mode.
-
- However, note that the implementation is more than a little bogus,
- in that there is code in /usr/X11R6/lib/libXdpms.a to implement all
- the usual server-extension-querying utilities -- but there are no
- prototypes in any header file! Thus, the prototypes here. (The
- stuff in X11/extensions/dpms.h and X11/extensions/dpmsstr.h define
- the raw X protcol, they don't define the API to libXdpms.a.)
