user should allocate a variable of type "struct sp_port *" and pass a pointer
to this to receive the result.
Returns: SP_OK on success, SP_ERR_FAIL on failure, SP_ERR_MEM on allocation failure,

the value pointed to by port_ptr will be set to NULL.
The result should be freed after use by calling sp_free_port().

Otherwise, it will be set to point to the newly allocated port.
