If keypad +mode is on for the window, \fBKEY_LEFT\fR and \fBKEY_BACKSPACE\fR +are both considered equivalent to the user's kill character. + +Characters input are echoed only if \fBecho\fR is currently on. In that case, +backspace is echoed as deletion of the previous character (typically a left +motion). + +The effect of +\fBwget_wstr\fR +is as though a series of +calls to +\fBwget_wch\fR +were made. + +The effect of +\fBmvget_wstr\fR +is as though a call to +\fBmove\fR +and then a series of calls to +\fBget_wch\fR +were +made. + +The effect of +\fBmvwget_wstr\fR +is as though a call to +\fBwmove\fR +and then a series of calls to +\fBwget_wch\fR +were made. + +The +\fBgetn_wstr\fR, +\fBmvgetn_wstr\fR, +\fBmvwgetn_wstr\fR, and +\fBwgetn_wstr\fR +functions are identical +to the +\fBget_wstr\fR, +\fBmvget_wstr\fR, +\fBmvwget_wstr\fR, and +\fBwget_wstr\fR +functions, respectively, +except that the +\fB*n_*\fR +versions read at most +\fIn\fR +characters, letting the application prevent overflow of the +input buffer. +.SH NOTES +Using +\fBget_wstr\fR, +\fBmvget_wstr\fR, +\fBmvwget_wstr\fR, or +\fBwget_wstr\fR +to read a line that +overflows the array pointed to by +\fBwstr\fR +causes undefined +results. +The use of +\fBgetn_wstr\fR, +\fBmvgetn_wstr\fR, +\fBmvwgetn_wstr\fR, or +\fBwgetn_wstr\fR, respectively, is recommended. + +These functions cannot return \fBKEY_\fR values because there +is no way to distinguish a \fBKEY_\fR value from a valid \fBwchar_t\fR value. + +All of these routines except \fBwgetn_wstr\fR may be macros. +.SH RETURN VALUES +All of these functions return \fBOK\fR upon successful completion. +Otherwise, they return \fBERR\fR. +.SH PORTABILITY +These functions are described in The Single Unix Specification, Version 2. +No error conditions are defined. +This implementation returns ERR if the window pointer is null, +or if the lower-level \fBwget_wch\fR call returns an ERR. +In the latter case, +an ERR return without other data is treated as an end-of-file condition, +and the returned array contains a \fBWEOF\fR followed by a null \fBwchar_t\fR. +.PP +X/Open curses documents these functions to pass an array of \fBwchar_t\fR, +but all of the vendors implement this using \fBwint_t\fR. +.SH SEE ALSO +Functions: +\fBcurses\fR(3X), +\fBcurs_get_wch\fR(3X), +\fBcurs_getstr\fR(3X). +.\"# +.\"# The following sets edit modes for GNU EMACS +.\"# Local Variables: +.\"# mode:nroff +.\"# fill-column:79 +.\"# End: |
