Name

dce_attr_sch_cursor_init - Initializes and allocates a cursor used with dce_attr_sch_scan()

Synopsis

#include <dce/dce_attr_base.h> void dce_rgy_attr_cursor_init(
dce_attr_sch_handle_t h,
unsigned32 ∗cur_num_entries,
dce_attr_cursor_t ∗cursor,
error_status_t ∗status);

Parameters

Input

hAn opaque handle bound to a schema object.  Use dce_attr_sch_bind() to acquire the handle. 

Output

cur_num_entries
A pointer to an unsigned 32-bit integer that specifies the total number of entries contained in the schema at the time of this call.

cursorA pointer to a dce_attr_cursor_t that is initialized to the first entry in the the schema. 

statusA pointer to the completion status.  On successful completion, the call returns error_status_ok.  Otherwise, it returns an error. 

Description

The dce_attr_sch_cursor_init() routine initializes and allocates a cursor used with the dce_attr_sch_scan() routine.  This call makes remote calls to initialize the cursor.  To limit the number of remote calls, use the dce_attr_sch_cursor_alloc() routine to allocate cursor, but not initialize it.  If the cursor input to dce_attr_sch_scan() has not been initialized, dce_attr_sch_scan() routine will initialize it; if it has been initialized, dce_attr_sch_scan() advances it. 

Unlike the dce_attr_sch_cursor_alloc() routine, the dce_attr_sch_cursor_init() routine supplies the total number of entries found in the schema as an output parameter. 

Permissions Required

None.
