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

SYNOPSIS
     #include 
     #include 



     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 allocated.


     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  allo-
     cated space.

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

SEE ALSO
     rmalloc(9F), rmallocmap(9F), rmfree(9F), rmfreemap(9F)
