inwstr, innwstr, winwstr, winnwstr, mvinwstr, mvinnwstr, mvwinwstr, mvwinnwstr - get a string of wchar_t characters from a curses window
#include <curses.h> int inwstr(wchar_t *wstr); int innwstr(wchar_t *wstr, int n); int winwstr(WINDOW *win, wchar_t *wstr); int winnwstr(WINDOW *win, wchar_t *wstr, int n); int mvinwstr(int y, int x, wchar_t *wstr); int mvinnwstr(int y, int x, wchar_t *wstr, int n); int mvwinwstr(WINDOW *win, int y, int x, wchar_t *wstr); int mvwinnwstr(WINDOW *win, int y, int x, wchar_t *wstr, int n);
These routines return a string of wchar_t wide characters in wstr, extracted starting at the current cursor position in the named window. The four functions with n as the last argument return a leading substring at most n characters long (exclusive of the trailing NUL). Transfer stops at the end of the current line, or when n characters have been stored at the location referenced by wstr. If the size n is not large enough to store a complete complex character, an error is generated.
All routines except winnwstr may be macros. Each cell in the window holds a complex character (i.e., base- and combining-characters) together with attributes and color. These functions store only the wide characters, ignoring attributes and color. Use in_wchstr to return the complex characters from a window.
All routines return ERR upon failure. Upon successful completion, the *inwstr routines return OK, and the *innwstr routines return the number of characters read into the string. Functions with a “mv” prefix first perform a cursor movement using wmove, and return an error if the position is outside the window, or if the window pointer is null.
