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 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 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.
