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.)
