| ### Synopsis |
| |
| int insch(chtype ch); |
| int winsch(WINDOW *win, chtype ch); |
| int mvinsch(int y, int x, chtype ch); |
| int mvwinsch(WINDOW *win, int y, int x, chtype ch); |
| |
| int insrawch(chtype ch); |
| int winsrawch(WINDOW *win, chtype ch); |
| int mvinsrawch(int y, int x, chtype ch); |
| int mvwinsrawch(WINDOW *win, int y, int x, chtype ch); |
| |
| 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. |
| |
| ### Portability |
| X/Open ncurses NetBSD |
