 DEVMAP_SET_CTX_TIMEOUT 9F "Jan 16, 2006"
 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
illumos DDI specific (illumos 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.
