Allocates a contiguous block of contiguous real memory for exclusive use by the caller. The block of memory reserved will be the size of a system LMB.
The alloclmb() subroutine reserves an LMB sized block of contiguous real memory for exclusive use by the caller. It returns the partition logical address of that memory in *laddr.
alloclmb() is only valid in an LPAR environment, and it fails (with ENOTSUP) if called in another environment.
Only a privileged user should call alloclmb().
| Item | Description |
