ddi_dma_free_handle(9F) Kernel Functions for Drivers ddi_dma_free_handle(9F)NAME
ddi_dma_free_handle - free DMA handle
SYNOPSIS
#include <sys/ddi.h>
#include <sys/sunddi.h>
void ddi_dma_free_handle(ddi_dma_handle_t *handle);
PARAMETERS
handle A pointer to the DMA handle previously allocated by a call to ddi_dma_alloc_handle(9F).
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI).
DESCRIPTION
ddi_dma_free_handle() destroys the DMA handle pointed to by handle. Any further references to the DMA handle will have undefined
results. Note that ddi_dma_unbind_handle(9F) must be called prior to ddi_dma_free_handle() to free any resources the system may be
caching on the handle.
CONTEXT
ddi_dma_free_handle() can be called from user, kernel, or interrupt context.

Why do shell builtins like echo and pwd have binaries in /bin? When I do which pwd, I get the one in /bin. that means that I am not using the builtin version? What determines which one gets used? Is the which command a definitive way to determine what is being run when I enter pwd? (16 Replies)

I have seen some misinformation regarding Unix file permissions. I will try to set the record straight. Take a look at this example of some output from ls:
$ ls -ld /usr/bin /usr/bin/cat

I see lot of ad-hoc shell scripts in our servers which don't have a shebang at the beginning .
Does this mean that it will run on any shell ?
Is it a good practice to create scripts (even ad-hoc ones) without shebang ? (16 Replies)

Hi all,
I am learning POSIX shell programming, and the book I read, uses the let command for integer arithmetic.
I have downloaded and use the shellcheck program on Linux.
This programs says:
In POSIX sh, 'let' is undefined.
See the screenshot attached.

I don't know how to start this but here goes.
I've been "using" Linux for over 10 years, possibly more and I still feel like I'm nowhere
where I should be. I'll be fair most of my time was spent either figuring out how
to run games on *nix at the time but as I got older and "wiser" I... (8 Replies)

Hi all, (mainly Neo)...
I keep noticing that the SQRT code I wrote recently for a POSIX shell keeps appearing, (the green colour sticks out like a sore thumb).
So I decided to take a look on Google.
Guess what?
