Global Variables
----------------

   This is the list of all the global variables present in the client
library:

`int gpm_flag'
     Initially zero, it is used to tell if the process is connected
     with a mouse server or not. It is used as a counter to manage
     multiple opens as well.

`int gpm_tried'
     A flag, used to avoid retrying a connection if the server is not
     available on the system.

`int gpm_fd'
     Initially `-1', it is the file descriptor used to talk with the
     server. If we run under xterm, it will be -2.

`int gpm_zerobased'
     Since selection and curses has always been one-based, this
     variable, zero by default, can be used to trigger zero-based
     coordinates in event reporting. It must be set before opening the
     mouse connection, and never changed later.  Note: Events.

`int gpm_visiblepointer'
     If not zero, causes the mouse cursor to be always visible on the
     window. It is zero by default.

`gpm_mx'
`gpm_my'
     These variables (max X and max Y) are used when fitting events
     inside the screen.  They are initialized by `Gpm_Open', and
     updated by a `SIGWINCH' handler internal to the library.  (Don't
     worry, the library doesn't _replace_ any `SIGWINCH' handler your
     program may already have installed; instead the library _hooks_
     the signal, that is, it calls any preexisting handler after taking
     care of its own needs.)

`int gpm_hflag'
     Used to signal if a character has been generated by a mouse
     handler.  Note: Handling Functions.

`Gpm_Handler *gpm_handler; void *gpm_data'
     Both initially `NULL', they're used to setup asynchronous mouse
     handling, as described below under the `Gpm_Getc()' item.

`gpm_morekeys'
     Used by the mouse handler to provide more than one key: if
     `gpm_morekeys' is not zero, `Gpm_Getc' will invoke the handler
     without waiting for events. `gpm_morekeys' is never set by the
     mouse library.
