SYNOPSIS

     #include <sys/ddi.h>

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

INTERFACE LEVEL

     Architecture independent level 1 (DDI/DKI).

DESCRIPTION

     rmalloc_wait()  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

     rmalloc_wait() returns the base of the allocated space.

CONTEXT

     This function can be called from user or interrupt  context.
     However,  in most cases rmalloc_wait() should be called from
     user context only.
