mod_drvdetach(D3) mod_drvdetach(D3)
NAME
mod_drvdetach - remove interrupts for a loadable device driver
SYNOPSIS
#include <sys/moddefs.h>
#include <sys/ddi.h>
void mod_drvdetach(void *iip);
Arguments
iip Pointer to the driver's prefixattach_info structure.
DESCRIPTION
mod_drvdetach is called from a loadable driver's _unload(D2)
routine. It disables and removes interrupts for a driver
being dynamically unloaded from a running system.
USAGE
The prefixattach_info structure is defined and initialized by
the kernel configuration tools at the time the driver is
configured into the system. The definition of the attach_info
structure is not included in the DDI/DKI, and can change
across releases. It should be treated as a ``black box'' by
the driver; none of its fields may be referenced.
Return Values
None
Level
Base only.
Synchronization Constraints
Does not sleep.
Driver-defined basic locks and read/write locks may not be
held across calls to this function.
Driver-defined sleep locks may be held across calls to this
function.
Examples
See _load(D2) for an example of mod_drvdetach.
