devmap_set_ctx_timeout(9F)

NAME

     devmap_set_ctx_timeout - set the timeout value for the  con-
     text 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 con-
     text 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) call-
     back function.

CONTEXT

     devmap_set_ctx_timeout() can be called from user  or  inter-
     rupt context.
