form_userptr(3X)form_userptr(3X)NAME
form_userptr - associate application data with a form item
SYNOPSIS
#include <form.h>
int set_form_userptr(FORM *form, void *userptr);
void* form_userptr(const FORM *form);
DESCRIPTION
Every form and every form item has a field that can be used to hold application-specific data (that is, the form-driver code leaves it
alone). These functions get and set the form user pointer field.
RETURN VALUE
The function form_userptr returns NULL on error. The function set_form_userptr returns one of the following:
E_OK The routine succeeded.
E_SYSTEM_ERROR
System error occurred (see errno).
SEE ALSO curses(3X), form(3X).
NOTES
The header file <form.h> automatically includes the header file <curses.h>.
PORTABILITY
These routines emulate the System V forms 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

Greetings,
I'm trying to delete a file with a weird name from within Terminal on a Mac.
It's a very old file (1992) with null characters in the name: ââWord FinderÂŽ Plusâ˘.
Here are some examples of what I've tried:
12FX009:5 dpontius$ ls
ââWord FinderÂŽ Plusâ˘
12FX009:5 dpontius$ rm... (29 Replies)
