проклятие расширения указателя экрана (curses screen-pointer extension)
Примечание (Note)
This extension introduces some new names:
NCURSES_SP_FUNCS
This is set to the library patch-level number. In the
unextended library, this is zero (0), to make it useful for
checking if the extension is provided.
NCURSES_SP_NAME
The new functions are named using the macro NCURSES_SP_NAME,
which hides the actual implementation. Currently this adds
a '_sp' suffix to the name of the unextended function. This
manual page indexes the extensions showing the full name.
However the proper usage of these functions uses the macro,
to provide for the possibility of changing the naming
convention for specific library configurations.
NCURSES_SP_OUTC
This is a new function-pointer type to use in the screen-
pointer functions where an NCURSES_OUTC is used in the
unextended library.
NCURSES_OUTC
This is a function-pointer type used for the cases where a
function passes characters to the output stream, e.g.,
vidputs(3X).
