rsm_create_localmemory_handle(3RSM)		      Remote Shared Memory Library Functions		       rsm_create_localmemory_handle(3RSM)

NAME

       rsm_create_localmemory_handle, rsm_free_localmemory_handle - create or free local memory handle

SYNOPSIS

       cc [ flag... ] file... -lrsm [ library... ]
       #include <rsmapi.h>

       int rsm_create_localmemory_handle(
	    rsmapi_controller_handle_t handle,
	    rsm_localmemory_handle_t *l_handle,
	    caddr_t local_vaddr, size_t length);

       int rsm_free_localmemory_handle(
	    rsmapi_controller_handle_t handle,
	    rsm_localmemory_handle_t l_handle);

DESCRIPTION

       The   rsm_create_localmemory_handle() and rsm_free_localmemory_handle() functions are supporting functions for rsm_memseg_import_putv(3RSM)
       and rsm_memseg_import_getv(3RSM).

       The rsm_create_localmemory_handle() function creates a local memory handle to be used in the I/O vector component of a scatter-gather  list
       of  subsequent  rsm_memseg_import_putv()  and  rsm_memseg_import_getv() calls. The handle argument specifies the controller handle obtained
       from rsm_get_controller(3RSM). The l_handle argument is a pointer to the location for the function to return the local memory  handle.  The
       local_vaddr argument specifies the local virtual address; it should be aligned at a page boundary. The length argument specifies the length
       of memory spanned by the handle.

       The rsm_free_localmemory_handle() function unlocks the memory range for the local handle specified by l_handle and releases the	associated
       system  resources. The handle argument specifies the controller handle.	All handles created by a process are freed when the process exits,
       but the process should call rsm_free_localmemory_handle() as soon as possible to free the system resources.

RETURN VALUES

       Upon successful completion, these functions return 0. Otherwise, an error value is returned to indicate the error.

ERRORS

       The rsm_create_localmemory_handle() and rsm_free_localmemory_handle() functions can return the following errors:

       RSMERR_BAD_CTLR_HNDL	    Invalid controller handle.

       RSMERR_BAD_LOCALMEM_HNDL     Invalid local memory handle.

       The  rsm_create_localmemory_handle() function can return the following errors:

       RSMERR_BAD_LENGTH	   Invalid length.

       RSMERR_BAD_ADDRESS	   Invalid address.

       RSMERR_INSUFFICIENT_MEM	   Insufficient memory.
