Видео атрибуты (Video attributes)
The following video attributes, defined in <curses.h>, can be
passed to the routines attron, attroff, and attrset, or OR'd with
the characters passed to addch (see curs_addch(3X)).

A_NORMAL Normal display (no highlight)
A_STANDOUT Best highlighting mode of the terminal.
A_UNDERLINE Underlining
A_REVERSE Reverse video
A_BLINK Blinking

A_BOLD Extra bright or bold
A_PROTECT Protected mode
A_INVIS Invisible or blank mode
A_ALTCHARSET Alternate character set
A_ITALIC Italics (non-X/Open extension)

These video attributes are supported by attr_on and related
functions (which also support the attributes recognized by
attron, etc.):

The return values of many of these routines are not meaningful
(they are implemented as macro-expanded assignments and simply
return their argument). The SVr4 manual page claims (falsely)
that these routines always return 1.
