PDCurses provides an alternative implementation of the curses library standard in addition to tinycurses. Where tinycurses is really tiny, PDCurses is more complete and provides virtually unlimited windows and the full API. The PDCurses code is brought in "vanilla", with all local changes residing in curses/pdcurses-backend/ In addition to a curses library, this change also provides libpanel (as part of the PDCurses code), and libform and libmenu which were derived from ncurses-5.9. As they rely on ncurses internals (and PDCurses is not ncurses), more changes were required for these libraries to work. The build system is extended to install the right set of header files depending on the selected curses implementation.

Synopsis:
|
|
chtype inch(void);
|
|
chtype winch(WINDOW *win);
|
|
chtype mvinch(int y, int x);
|
|
chtype mvwinch(WINDOW *win, int y, int x);

int in_wch(cchar_t *wcval);
|
|
int win_wch(WINDOW *win, cchar_t *wcval);
|
|
int mvin_wch(int y, int x, cchar_t *wcval);
|
|
int mvwin_wch(WINDOW *win, int y, int x, cchar_t *wcval);
|
|
|
|
Description:
|
|
The inch() functions retrieve the character and attribute from
|
|
the current or specified window position, in the form of a
|
|
chtype. If a NULL window is specified, (chtype)ERR is returned.
|
|
|
|
The in_wch() functions are the wide-character versions; instead
|
|
of returning a chtype, they store a cchar_t at the address
|
|
specified by wcval, and return OK or ERR. (No value is stored
|
|
when ERR is returned.) Note that in PDCurses, chtype and cchar_t
|
|
are the same.
