qunbufcall(9F) Kernel Functions for Drivers qunbufcall(9F)NAME
qunbufcall - cancel a pending qbufcall request
SYNOPSIS
#include <sys/stream.h>
#include <sys/ddi.h>
void qunbufcall(queue_t *q, bufcall_id_t id);
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI).
PARAMETERS
q Pointer to STREAMS queue_t structure.
id Identifier returned from qbufcall(9F)DESCRIPTION
qunbufcall() cancels a pending qbufcall() request. The argument id is a non-zero identifier of the request to be cancelled. id is returned
from the qbufcall() function used to issue the cancel request.
The qunbufcall() function is tailored to be used with the enhanced STREAMS framework interface which is based on the concept of perimeters.
(See mt-streams(9F).) qunbufcall() returns when the bufcall has been cancelled or finished executing. The bufcall will be cancelled even
if it is blocked at the perimeters associated with the queue. All outstanding timeouts and bufcalls must be cancelled before a driver close
routine can block and before the close routine calls qprocsoff(9F).
CONTEXT
qunbufcall() can be called from user or interrupt context.

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)
