NAME
curses — screen functions with “optimal” cursor motionLIBRARY
Curses Library (libcurses, -lcurses)SYNOPSIS
| cc | [flags] files -lcurses [libraries] |
DESCRIPTION
These routines give the user a method of updating screens with reasonable optimization. They keep an image of the current screen, and the user sets up an image of a new one. Then the refresh() tells the routines to make the current screen look like the new one. In order to initialize the routines, the routine initscr() must be called before any of the other routines that deal with windows and screens are used. The routine endwin() should be called before exiting. The routine start_color() must be called before any of the other routines that deal with color are used.FUNCTIONS
ENVIRONMENT
- COLUMNS
- The number of columns in the terminal if set. This is usually automatically configured by querying the kernel.
- CURSES_TRACE_MASK
- An integer mask that enables specific debugging traces. Enabled only in the debug build of curses.
- CURSES_TRACE_FILE
- A file where to output debugging information. Enabled only in the debug build of curses.
- ESCDELAY
- The maximum delay in milliseconds between characters in multi-character keystrokes (such are arrow keys) where the adjacent characters are considered part of the same multi-character sequence. The default is 300 milliseconds.
- LINES
- The number of lines in the terminal if set. is usually automatically configured by querying the kernel.
- TERM
- The terminal type of the current terminal.
