int ins_wch(const cchar_t *wch);
|
|
int wins_wch(WINDOW *win, const cchar_t *wch);
|
|
int mvins_wch(int y, int x, const cchar_t *wch);
|
|
int mvwins_wch(WINDOW *win, int y, int x, const cchar_t *wch);
|
|
|
|
Description:
|
|
The insch() functions insert a chtype into the window at the
|
|
current or specified cursor position. The cursor is NOT
|
|
advanced. A newline is equivalent to clrtoeol(); tabs are
|
|
expanded; other control characters are converted as with
|
|
unctrl().
|
|
|
|
The ins_wch() functions are the wide-character
|
|
equivalents, taking cchar_t pointers rather than chtypes.
|
|
|
|
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 using inch() and insch().
|
|
|
|
insrawch() etc. are PDCurses-specific wrappers for insch() etc.
|
|
that disable the translation of control characters.
|
|
|
|
Return Value:
|
|
All functions return OK on success and ERR on error.
