NAME
       rsm_get_controller, rsm_get_controller_attr, rsm_release_controller - get or release a controller handle

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

       int rsm_get_controller(char *name, rsmapi_controller_handle_t *controller);

       int rsm_get_controller_attr(rsmapi_controller_handle_t chdl, rsmapi_controller_attr_t *attr);

       int rsm_release_controller(rsmapi_controller_handle_t chdl);

DESCRIPTION
       The  controller	functions  provide mechanisms for obtaining access to a controller, determining the characteristics of the controller, and
       releasing the controller.

       The  rsm_get_controller() function acquires a controller handle through the controller argument.  The name argument is  the  specific  con-
       troller instance (for example, "sci0" or "loopback"). This controller handle is used for subsequent RSMAPI calls.

       The  rsm_get_controller_attr()  function  obtains  a controller's attributes through the attr argument. The chdl argument is the controller
       handle obtained by the	rsm_get_controller() call. The attribute structure is defined in the <rsmapi> header.

       The  rsm_release_controller() function releases the resources associated with the controller identified	by  the  controller  handle  chdl,
       obtained  by  calling   rsm_get_controller(). Each rsm_release_controller() call must have a corresponding rsm_get_controller() call. It is
       illegal to access a controller or segments exported or imported using a released controller.

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

ERRORS
       The rsm_get_controller(), rsm_get_controller_attr(), and rsm_release_controller() functions can return the following errors:

       RSMERR_BAD_CTLR_HNDL	       Invalid controller handle.

       The rsm_get_controller() and  rsm_get_controller_attr() functions can return the following errors:

       RSMERR_BAD_ADDR		       Bad address.

       The  rsm_get_controller() function can return the following errors:

       RSMERR_CTLR_NOT_PRESENT	       Controller not present.

       RSMERR_INSUFFICIENT_MEM	       Insufficient memory.

       RSMERR_BAD_LIBRARY_VERSION      Invalid library version.
