    NAME

    instr,
    innstr,
    winstr,
    winnstr,
    mvinstr,
    mvinnstr,
    mvwinstr,
    mvwinnstr - get a string of characters from a curses window
     
    

    SYNOPSIS

    #include <curses.h>

    int instr(char *str);
    int innstr(char *str, int n);
    int winstr(WINDOW *win, char *str);
    int winnstr(WINDOW *win, char *str, int n);
    int mvinstr(int y, int x, char *str);
    int mvinnstr(int y, int x, char *str, int n);
    int mvwinstr(WINDOW *win, int y, int x, char *str);
    int mvwinnstr(WINDOW *win, int y, int x, char *str, int n);
     

    DESCRIPTION

    These routines return a string of characters in str, 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 characters long (exclusive of the trailing NUL).  

    RETURN VALUE

    All of the functions return ERR upon failure, or the number of characters actually read into the string.

    X/Open defines no error conditions. In this implementation, if the window parameter is null or the str parameter is null, a zero is returned.  

    NOTES

    Note that all routines except winnstr may be macros.  

    PORTABILITY

    SVr4 does not document whether a length limit includes or excludes the trailing NUL.

    The ncurses library extends the XSI description by allowing a negative value for n. In this case, the functions return the string ending at the right margin.  

    SEE ALSO

    curses(3X).
