rmalloc_wait(D3)
rmalloc_wait - allocate space from a private space management map
As shipped in IRIX 6.5.19. Unchanged since IRIX 6.5.
NAME rmalloc_wait - allocate space from a private space management map SYNOPSIS #include <sys/types.h> #include <sys/map.h> #include <sys/ddi.h> ulong_t rmalloc_wait(struct map *mp, size_t size); Arguments mp Pointer to map to resource map. size Number of units to allocate. DESCRIPTION rmalloc_wait allocates space from a private map previously allocated using rmallocmap(D3). Return Values rmalloc_wait returns the base of the allocated space. USAGE rmalloc_wait is identical to rmalloc(D3), except that a call to rmalloc_wait will sleep (uninterruptible by signals), if necessary, until space becomes available. Space allocated using rmalloc_wait may be returned to the map using rmfree(D3). Level Base only. Synchronization Constraints May sleep. Driver-defined basic locks and read/write locks may not be held across calls to this function. Driver-defined sleep locks may be held across calls to this function, but the driver writer must be cautious to avoid deadlock between the process holding the lock and trying to acquire the resource and another process holding the resource and trying to acquire the lock.
