DP_XMFREE(2-N)             SYSTEM CALLS            DP_XMFREE(2-N)


NAME
     dp_xmfree -- detach a global memory region


SYNOPSIS
     #include <sys/mppg.h>

     int dp_xmfree(void *addr);


DESCRIPTION
     dp_xmfree  detaches  a global memory region from the calling
     process's process virtual space.  When there is  no  process
     referring  to  the detached global memory region, the global
     memory region is removed.  The removed global memory  region
     is also detached from the global virtual space.

     addr  specifies  the start address of a global memory region
     on the process virtual space.

     dp_xmfree fails if the following is true:

     [EINVAL]   addr is not a start address of  a  global  memory
                region.
