 .SH DESCRIPTION
-These functions are used to simplify analysis of memory leaks in the ncurses
-library.
-They are normally not available; they must be configured into the library
-at build time using the \fB\-\-disable-leaks\fP option.
-That compiles-in code that frees memory that normally would not be freed.
+These functions are used to simplify analysis of memory leaks in the
+\fI\%ncurses\fP library.
 .PP
 Any implementation of curses must not free the memory associated with
-a screen, since (even after calling \fBendwin\fP), it must be available
-for use in the next call to \fBrefresh\fP.
+a screen, since (even after calling \fB\%endwin\fP(3X)), it must be available
+for use in the next call to \fB\%refresh\fP(3X).
 There are also chunks of memory held for performance reasons.
 That makes it hard to analyze curses applications for memory leaks.
-To work around this, one can build a debugging version of the ncurses
-library which frees those chunks which it can, and provides these
-functions to free all of the memory allocated by the ncurses library.
+When using the specially configured debugging version of the
+\fI\%ncurses\fP library,
+applications can call functions which free those chunks of memory,
+simplifying the process of memory-leak checking.
 .PP
-The \fP_nc_free_and_exit\fP function is the preferred one since
-some of the memory which is freed may be required for the application
-to continue running.
-Its parameter is the code to pass to the \fPexit\fP routine.
+Some of the functions are named with a \*(``_nc_\*('' prefix
+because they are not intended for use in the non-debugging library:
+.TP 5
+\fB\%_nc_freeall\fP
+This frees (almost) all of the memory allocated by \fI\%ncurses\fP.
+.TP 5
+\fB\%_nc_free_and_exit\fP
+This frees the memory allocated by \fI\%ncurses\fP
+(like \fB\%_nc_freeall\fP),
+and exits the program.
+It is preferred over \fB\%_nc_freeall\fP since some of that memory
+may be required to keep the application running.
+Simply exiting (with the given exit-code) is safer.
+.TP 5
+\fB\%_nc_free_tinfo\fP
+Use this function if only the low-level terminfo functions (and
+corresponding library) are used.
+Like \fB\%_nc_free_and_exit\fP, it exits the program after freeing memory.
+.PP
+The functions prefixed \*(``_nc\*('' are normally not available;
+they must be configured into the library
+at build time using the \fB\%\-\-disable-leaks\fP option.
+That compiles-in code that frees memory that normally would not be freed.
+.PP
+The \fB\%exit_curses\fP and \fB\%exit_terminfo\fP functions
+call \fB\%_nc_free_and_exit\fP and \fB\%_nc_free_tinfo\fP if
+the library is configured to support memory-leak checking.
+If the library is not configured to support memory-leak checking,
+they simply call \fBexit\fP.
 .SH RETURN VALUE
 These functions do not return a value.
 .SH PORTABILITY
-These functions are not part of the XSI interface.
+These functions are not part of X/Open Curses;
+nor do other implementations of curses provide a similar feature.
+.PP
+In any implementation of X/Open Curses, an application can free part
+of the memory allocated by curses:
+.bP
+The portable part of \fB\%exit_curses\fP can be freed using \fB\%delscreen\fP,
+passing the \fISCREEN\fP pointer returned by \fB\%newterm\fP.
+.IP
+In some implementations, there is a global variable \fBsp\fP
+which could be used, e.g., if the screen were only initialized
+using \fB\%initscr\fP.
+.bP
+The portable part of \fB\%exit_terminfo\fP can be freed
+using \fB\%del_curterm\fP.
+.IP
+In this case, there is a global variable \fB\%cur_term\fP which can be
+used as parameter.
