consoleheight

Consoleheight is a term used to describe the height of a computer console or terminal window, typically expressed as the number of text rows that are visible in the active view. It directly affects how much output can be displayed at once, how lines wrap, and how paging tools present content.

Measurement and reporting vary by platform. In Unix-like environments, the height is commonly referred to as the number of rows in the terminal. The value may be exposed by the environment as LINES, and programs can query it via terminal APIs. In C, a common method is to use ioctl with TIOCGWINSZ to read a struct winsize, whose ws_row field expresses the height. Languages with standard libraries (for example Python or Node.js) expose terminal dimensions via functions that return rows or lines.

In Windows, the console height comes from the current visible window dimensions rather than the full screen buffer. The Win32 API GetConsoleScreenBufferInfo returns a CONSOLE_SCREEN_BUFFER_INFO structure; the srWindow rectangle defines the visible window, and its height is Bottom minus Top plus 1.

Practical use and behavior. Programs use consoleheight to format output, implement pagination, or adjust interfaces for full-screen text UIs. Applications should respond to resize events when the console height changes, such as the SIGWINCH signal on Unix-like systems or console resize events on Windows.

Note: The term consoleheight is descriptive rather than a fixed API name; implementations typically refer to terminal height, window height, or lines/rows depending on the platform and language.
