Synopsis:
|
||||
int getstr(char *str);
|
||||
int wgetstr(WINDOW *win, char *str);
|
||||
int mvgetstr(int y, int x, char *str);
|
||||
int mvwgetstr(WINDOW *win, int y, int x, char *str);
|
||||
int getnstr(char *str, int n);
|
||||
int wgetnstr(WINDOW *win, char *str, int n);
|
||||
int mvgetnstr(int y, int x, char *str, int n);
|
||||
int mvwgetnstr(WINDOW *win, int y, int x, char *str, int n);
|
||||
|
||||
int get_wstr(wint_t *wstr);
|
||||
int wget_wstr(WINDOW *win, wint_t *wstr);
|
||||
int mvget_wstr(int y, int x, wint_t *wstr);
|
||||
int mvwget_wstr(WINDOW *win, int, int, wint_t *wstr);
|
||||
int getn_wstr(wint_t *wstr, int n);
|
||||
int wgetn_wstr(WINDOW *win, wint_t *wstr, int n);
|
||||
int mvgetn_wstr(int y, int x, wint_t *wstr, int n);
|
||||
int mvwgetn_wstr(WINDOW *win, int y, int x, wint_t *wstr, int n);
|
||||
|
||||
Description:
|
||||
These routines call wgetch() repeatedly to build a string,
|
||||
interpreting erase and kill characters along the way, until a
|
||||
newline or carriage return is received. When PDCurses is built
|
||||
with wide-character support enabled, the narrow-character
|
||||
functions convert the wgetch()'d values into a multibyte string
|
||||
in the current locale before returning it. The resulting string
|
||||
is placed in the area pointed to by *str. The routines with n as
|
||||
the last argument read at most n characters.
|
||||
|
||||
Note that there's no way to know how long the buffer passed to
|
||||
wgetstr() is, so use wgetnstr() to avoid buffer overflows.
|
||||
|
||||
Return Value:
|
||||
This functions return ERR on failure or any other value on
|
||||
success.
