readchar
The readchar function waits for an event from the keyboard and returns the next character typed by a user. NetHack has many reasons to need to wait for your command: you might on the map, at a menu, at a "-- More --" prompt, or elsewhere. The readchar functions acts as a gate through which all of these places obtain your instruction. Most of the calls to readchar are elsewhere in cmd.c, though two are in invent.c.

The C language getchar function waits for a character on the standard input and use it. Though the tty window port could use getchar to access keyboard events, the other window ports must use different mechanisms, like X11 events or Qt signals.
Thus, the DevTeam now uses a Getchar macro (starting with an uppercase G). This macro calls a window-port-specific function to grab the key. Thus the Getchar macro takes the place of the getchar function that NetHack used when it was a tty-only game.
Given this, it seems strange that the NR_OF_EOFS code is here. On a SYSV system, NR_OF_EOFS became 20 at cmd.c#line14. This crude hack attempts to distinguish a permanent end-of-file (EOF) from a temporary interruption by re-reading the character 20 times. (The more correct way to do this would be to check the global errno variable for the EINTR error from the Unix read system call.) The strange situation is that this hack calls clearerr(stdin) even if standard input is not the source of our key events. It would be reasonable to move this code to the tty-specific implementation of the Getchar function.
Other than calling Getchar, the readchar function also needs to worry about mouse clicks from window ports that support them. It deals with them by calling the click_to_cmd function to translate the mouse click into equivalent key events. It then stores the key characters in the readchar_queue. Until this queue is empty, subsequent calls to readchar use this queue instead of requesting another event from Getchar.
