PARAMETERS

22       dhp      An opaque mapping handle that the system uses to describe  the

DESCRIPTION

31       The devmap_set_ctx_timeout() function specifies the time  interval  for
32       the  system  to  wait  between successive calls to the driver's context
33       management callback function, devmap_contextmgt(9E).
34
35
36       Device  drivers  typically   call   devmap_set_ctx_timeout()   in   the
37       devmap_map(9E) routine. If the drivers do not call devmap_set_ctx_time‐
38       out() to set the timeout value, the default timeout  value  of  0  will
39       result in no delay between successive calls to the driver's devmap_con‐
40       textmgt(9E) callback function.
41

CONTEXT

43       The devmap_set_ctx_timeout() function can be called from  user,  inter‐
44       rupt, or kernel context.
