devmap_set_ctx_timeout 9F "16 Jan 2006" "SunOS 5.11" "Kernel Functions for Drivers"
NAME
devmap_set_ctx_timeout - set the timeout value for the context management callback
SYNOPSIS

#include <sys/ddi.h>
#include <sys/sunddi.h>



void devmap_set_ctx_timeout(devmap_cookie_t dhp, clock_t ticks);
INTERFACE LEVEL

Solaris DDI specific (Solaris DDI).

PARAMETERS

dhp

An opaque mapping handle that the system uses to describe the mapping.

ticks

Number of clock ticks to wait between successive calls to the context management callback function.

DESCRIPTION

The devmap_set_ctx_timeout() function specifies the time interval for the system to wait between successive calls to the driver's context management callback function, devmap_contextmgt(9E).

Device drivers typically call devmap_set_ctx_timeout() in the devmap_map(9E) routine. If the drivers do not call devmap_set_ctx_timeout() to set the timeout value, the default timeout value of 0 will result in no delay between successive calls to the driver's devmap_contextmgt(9E) callback function.

CONTEXT

The devmap_set_ctx_timeout() function can be called from user, interrupt, or kernel context.
