Name: pdcsetsc
Synopsis:
int PDC_set_blink(bool blinkon);
void PDC_set_title(const char *title);
Description:
PDC_set_blink() toggles whether the A_BLINK attribute sets an
actual blink mode (TRUE), or sets the background color to high
intensity (FALSE). The default is platform-dependent (FALSE in
most cases). It returns OK if it could set the state to match
the given parameter, ERR otherwise. Current platforms also
adjust the value of COLORS according to this function -- 16 for
FALSE, and 8 for TRUE.
PDC_set_title() sets the title of the window in which the curses
program is running. This function may not do anything on some
platforms. (Currently it only works in Win32 and X11.)
