NAME
       rmalloc_wait - allocate space from a resource map, wait if necessary

SYNOPSIS
       #include <sys/map.h>
       #include <sys/ddi.h>

       unsigned long rmalloc_wait(struct map *mp, size_t size);

INTERFACE LEVEL
       Architecture independent level 1 (DDI/DKI).

PARAMETERS
       mp
	       Pointer	to  the	 resource  map from which space is to be allo‐
	       cated.

       size
	       Number of units of space to allocate.

DESCRIPTION
       The rmalloc_wait() function requests an	allocation  of	space  from  a
       resource	 map.  rmalloc_wait()  is  similar to the rmalloc(9F) function
       with the exception that it will wait for space to become	 available  if
       necessary.

RETURN VALUES
       The rmalloc_wait() function returns the base of the allocated space.

CONTEXT
       This  function  can  be called from user, interrupt, or kernel context.
       However, in most cases rmalloc_wait() should not be called from	inter‐
       rupt context.
