DESCRIPTION The deleteln and wdeleteln routines do the following: Delete the line under the cursor in the current or specified window Move all lines be- low the current line up one line Clear the bottom line of the window These routines do not change the cursor position. (This does not imply use of a hardware delete line feature.) The insdelln and winsdelln routines do the following: For positive n, insert n lines into the current or specified window above the current line The n bottom lines are lost. For negative n, delete n lines (starting with the one under the cursor), and move the remaining lines up The bottom n lines are cleared. These routines do not change the current cursor position. The insertln and insertln routines insert a blank line above the cur- rent line. The bottom line is lost. (This does not imply use of a hardware insert line feature.) NOTES The header file curses.h automatically includes the header file stdio.h. Note that all routines except winsdelln may be macros. RETURN VALUES All routines return ERR upon failure and OK upon successful completion. RELATED INFORMATION Functions: curses(3) Others: standards(5) delim off curs_deleteln(3)
