rmalloc_wait

rmalloc_wait(9F)					   Kernel Functions for Drivers 					  rmalloc_wait(9F)

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

       rmalloc_wait()  requests  an allocation of space from a resource map. rmalloc_wait() is similar to the rmalloc(9F) function with the excep-
       tion 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.

SEE ALSO

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