Description:
|
||||
addch() adds the chtype ch to the default window (stdscr) at the
|
||||
current cursor position, and advances the cursor. Note that
|
||||
chtypes can convey both text (a single character) and
|
||||
attributes, including a color pair. add_wch() is the wide-
|
||||
character version of this function, taking a pointer to a
|
||||
cchar_t instead of a chtype.
|
||||
|
||||
waddch() is like addch(), but also lets you specify the window.
|
||||
(This is in fact the core output routine.) wadd_wch() is the
|
||||
wide version.
|
||||
|
||||
mvaddch() moves the cursor to the specified (y, x) position, and
|
||||
adds ch to stdscr. mvadd_wch() is the wide version.
|
||||
|
||||
mvwaddch() moves the cursor to the specified position and adds
|
||||
ch to the specified window. mvwadd_wch() is the wide version.
|
||||
|
||||
echochar() adds ch to stdscr at the current cursor position and
|
||||
calls refresh(). echo_wchar() is the wide version.
|
||||
|
||||
wechochar() adds ch to the specified window and calls
|
||||
wrefresh(). wecho_wchar() is the wide version.
|
||||
|
||||
addrawch(), waddrawch(), mvaddrawch() and mvwaddrawch() are
|
||||
PDCurses-specific wrappers for addch() etc. that disable the
|
||||
translation of control characters.
|
||||
|
||||
The following applies to all these functions:
|
||||
|
||||
If the cursor moves on to the right margin, an automatic newline
|
||||
is performed. If scrollok is enabled, and a character is added
|
||||
to the bottom right corner of the window, the scrolling region
|
||||
will be scrolled up one line. If scrolling is not allowed, ERR
|
||||
will be returned.
|
||||
|
||||
If ch is a tab, newline, or backspace, the cursor will be moved
|
||||
appropriately within the window. If ch is a newline, the
|
||||
clrtoeol routine is called before the cursor is moved to the
|
||||
beginning of the next line. If newline mapping is off, the
|
||||
cursor will be moved to the next line, but the x coordinate will
|
||||
be unchanged. If ch is a tab the cursor is moved to the next
|
||||
tab position within the window. If ch is another control
|
||||
character, it will be drawn in the ^X notation. Calling the
|
||||
inch() routine after adding a control character returns the
|
||||
representation of the control character, not the control
|
||||
character.
|
||||
|
||||
Video attributes can be combined with a character by ORing them
|
||||
into the parameter. Text, including attributes, can be copied
|
||||
from one place to another by using inch() and addch().
|
||||
|
||||
Note that in PDCurses, for now, a cchar_t and a chtype are the
|
||||
same. The text field is 16 bits wide, and is treated as Unicode
|
||||
(UCS-2) when PDCurses is built with wide-character support
|
||||
(define PDC_WIDE). So, in functions that take a chtype, like
|
||||
addch(), both the wide and narrow versions will handle Unicode.
|
||||
But for portability, you should use the wide functions.
|
||||
|
||||
Return Value:
|
||||
All functions return OK on success and ERR on error.
