Parameter	Data Type	Description
hCtx	ESS_HCTX_T	API context handle.
pSelectPartition	ESS_PARTSLCT_T	Criteria to select partitions.
pusCount	ESS_PUSHORT_T	Count of partitions returned.
ppPartition	ESS_PART_INFO_T	Pointer to allocated array of partition information structures.

Return Value

Returns zero if successful; error code if unsuccessful.
