winwstr.3ncurses

NAME

inwstr, innwstr, winwstr, winnwstr, mvinwstr, mvinnwstr, mvwinwstr, mvwinnwstr - get a string of wchar_t characters from a curses window

SYNOPSIS

 #include <curses.h> 
 
 int inwstr(wchar_t *str);
 
 int innwstr(wchar_t *str, int n);
 
 int winwstr(WINDOW *win, wchar_t *str);
 
 int winnwstr(WINDOW *win, wchar_t *str, int n);
 
 int mvinwstr(int y, int x, wchar_t *str);
 
 int mvinnwstr(int y, int x, wchar_t *str, int n);
 
 int mvwinwstr(WINDOW *win, int y, int x, wchar_t *str);
 
 int mvwinnwstr(WINDOW *win, int y, int x, wchar_t *str, int n);
 

DESCRIPTION

These routines return a string of wchar_t characters in wstr, extracted starting at the current cursor position in the named window. Attributes are stripped from the characters. The four functions with n as the last argument return a leading substring at most n bytes long (exclusive of the trailing NUL). Transfer stops at the end of the current line, or when n bytes have been stored at the location referenced by wstr.

If the size n is not large enough to store a complete character, an error is generated.

NOTES

Note that all routines except winnwstr may be macros.

RETURN VALUES

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.
