menu_userptr(3X)menu_userptr(3X)NAME
menu_userptr - associate application data with a menu item
SYNOPSIS
#include <menu.h>
int set_menu_userptr(MENU *menu, void *userptr);
void *menu_userptr(const MENU *menu);
DESCRIPTION
Every menu and every menu item has a field that can be used to hold application-specific data (that is, the menu-driver code leaves it
alone). These functions get and set the menu user pointer field.
RETURN VALUE
Except for menu_userptr (which returns NULL on error), each function returns one of the following:
E_OK The routine succeeded.
E_SYSTEM_ERROR
System error occurred (see errno).
SEE ALSO curses(3X), menu(3X).
NOTES
The header file <menu.h> automatically includes the header file <curses.h>.
PORTABILITY
These routines emulate the System V menu library. They were not supported on Version 7 or BSD versions.
The user pointer should be a void pointer. We leave it as a char pointer for SVr4 compatibility.

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
# When the shell exits, append to the history file instead of overwriting it

After the success of the jq - tool for parsing and manipulating JSON-Data someone wrote a tool called yq, which aims to be the same for YAML, what jq is for JSON. Seems to work fine. I'll definitely give it a chance in future.
