cursor(3MENU)

πŸ’… cursor(3MENU) β€” the library-calls girlies know πŸ’…

ok so bestie, we're in the 3MENU section of the manual (that's the Library calls corner of the house 🏠✨), and today's main character is cursor(3MENU). she's small, she's focused, she does ONE thing and she does it gorgeously. let's get into it πŸŽ€


✨ NAME ✨

pos_menu_cursor β€” position a menu's cursor πŸ–±οΈπŸ’–

like. that's the whole job. put the cursor where it belongs. iconic behaviour honestly.


🌸 SYNOPSIS 🌸

#include <menu.h>

int pos_menu_cursor(const MENU *menu);

look at her. one include, one function, one const MENU * argument. no drama, no extra params, just clean lines fr fr ✨


πŸ¦‹ DESCRIPTION πŸ¦‹

so what does pos_menu_cursor actually DO? she restores the cursor to the current position associated with the menu's selected item. that's it. that's the assignment and she ate πŸ’…

when is this a big deal tho? okay imagine this: some curses routines got called and did a lil screen-painting moment in response to a menu select 🎨 like you drew stuff on the screen and now your cursor is just… somewhere. lost. vibing in the wrong place 😭 that's when you call pos_menu_cursor β€” to bring the cursor back home to the item that's actually selected. main character restored to her rightful position πŸ‘‘


πŸ’– RETURN VALUE πŸ’–

this routine returns one of the following, and bestie we're reading them ALL:

  • E_OK β€” the routine succeeded ✨ slay, no notes.
  • E_SYSTEM_ERROR β€” a system error occurred (see errno(3)). something went wrong at the system level, go check your errno πŸ’€
  • E_BAD_ARGUMENT β€” the routine detected an incorrect or out-of-range argument πŸ™ˆ you handed her something she can't work with.
  • E_NOT_POSTED β€” the menu has not been posted πŸ‘€ no menu on screen = nothing to point at.
lowkey important: if you get anything other than E_OK, something is off. read the list, don't skip it 🫢

🌈 PORTABILITY 🌈

these routines emulate the System V menu library. they were not supported on Version 7 or BSD versions. so if you're on some ancient BSD situation… yeah, this one's not coming to your party 🧚 iykyk.
