curs_getstr - Linux

Overview

curs_getstr retrieves the current cursor location and stores it in a variable. It is primarily used to store the cursor’s coordinates for later manipulation or to capture user input from a specific location.

Syntax

curs_getstr(cursor, variable)

Parameters:

• cursor: The cursor variable to get the coordinates of.
• variable: The variable in which to store the coordinates.

Options/Flags

None

Examples

Simple:

Get the current cursor’s coordinates and store them in the variable cursor_pos:

curs_getstr(current_cursor, cursor_pos)

Complex:

Use curs_getstr in conjunction with cursor_set to move the cursor to a specific location on the screen:

curs_getstr(orig_cursor, orig_pos)
curs_set(5, 10)
curs_getstr(new_cursor, new_pos)
curs_set(orig_pos.row, orig_pos.col)

Common Issues

• Variable Error: Ensure that the variable used to store the coordinates is created and defined before using curs_getstr.

Integration

Combine curs_getstr with curs_set to create advanced cursor movements, such as scrolling or pagination.
