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

devmap_set_ctx_timeout() 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

devmap_set_ctx_timeout() can be called from user or interrupt context.

SEE ALSO

devmap_contextmgt(9E), devmap_map(9E), timeout(9F)
