PARAMETERS

21       mp      Pointer  to  the  resource  map from which space is to be allo‐

DESCRIPTION

29       The rmalloc_wait() function requests an  allocation  of  space  from  a
30       resource  map.  rmalloc_wait()  is  similar to the rmalloc(9F) function
31       with the exception that it will wait for space to become  available  if
32       necessary.
33

RETURN VALUES

35       The rmalloc_wait() function returns the base of the allocated space.
36

CONTEXT

38       This  function  can  be called from user, interrupt, or kernel context.
39       However, in most cases rmalloc_wait() should not be called from  inter‐
40       rupt context.
