/*man-start*********************************************************************
has_il() - determine whether insert/delete line available
X/Open Description:
This function will return TRUE if the terminal has insert line
and delete line capabilities.
PDCurses Description:
For DOS, this is irrelevant (and ALWAYS TRUE), as the speed of
the DIRECT VIDEO or even BIOS writes is quicker than on a
serial terminal.
For FLEXOS, this value has meaning and depends on the terminal,
though at this time, it is a constant TRUE.
X/Open Return Value:
The has_il() function returns TRUE if the terminal has insert
line and delete line capabilities, otherwise it returns
FALSE.
X/Open Errors:
No errors are defined for this function.
Portability:
PDCurses bool has_il( void );
X/Open Dec '88 bool has_il( void );
BSD Curses
SYS V Curses
