The rsm_memseg_import_init_barrier() function creates a barrier for the imported segment specified by memseg. The barrier type is specified by the type argument. Currently, only RSM_BAR_DEFAULT is supported as a barrier type. A handle to the barrier is obtained through the barrier argument and is used in subsequent barrier calls.

The rsm_memseg_import_destroy_barrier() function deallocates all the resources associated with the barrier.

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

The rsm_memseg_import_init_barrier() and rsm_memseg_import_destroy_barrier() functions can return the following errors:

RSMERR_BAD_SEG_HNDL

Invalid segment handle.

RSMERR_BAD_BARRIER_PTR

Invalid barrier pointer.

The rsm_memseg_import_init_barrier() function can return the following errors:

RSMERR_INSUFFICIENT_MEM

Insufficient memory.
