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

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



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

Architecture independent level 1 (DDI/DKI).

mp size

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.

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

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