### Synopsis
|
|
|
|
int PDC_set_blink(bool blinkon);
|
|
int PDC_set_bold(bool boldon);
|
|
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.
|
|
|
|
PDC_set_bold() toggles whether the A_BOLD attribute selects an actual
|
|
bold font (TRUE), or sets the foreground color to high intensity
|
|
(FALSE). It returns OK if it could set the state to match the given
|
|
parameter, ERR otherwise.
|
|
|
|
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.

|
|
