rmalloc_wait(D3)					      rmalloc_wait(D3)

NAME
     rmalloc_wait - allocate space from a private space management map

SYNOPSIS
     #include <sys/types.h>
     #include <sys/map.h>
     #include <sys/ddi.h>
     ulong_t rmalloc_wait(struct map *mp, size_t size);

   Arguments
     mp	       Pointer to map to resource map.

     size      Number of units to allocate.

DESCRIPTION
     rmalloc_wait allocates space from a private map previously allocated
     using rmallocmap(D3).

   Return Values
     rmalloc_wait returns the base of the allocated space.

USAGE
     rmalloc_wait is identical to rmalloc(D3), except that a call to
     rmalloc_wait will sleep (uninterruptible by signals), if necessary, until
     space becomes available.

     Space allocated using rmalloc_wait may be returned to the map using
     rmfree(D3).

   Level
     Base only.

   Synchronization Constraints
     May sleep.

     Driver-defined basic locks and read/write locks may not be held across
     calls to this function.

     Driver-defined sleep locks may be held across calls to this function, but
     the driver writer must be cautious to avoid deadlock between the process
     holding the lock and trying to acquire the resource and another process
     holding the resource and trying to acquire the lock.
