|         int insch(chtype ch);
 | |
|         int winsch(WINDOW *win, chtype ch);
 | |
|         int mvinsch(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.
