sec_rgy_attr_sch_scan-Read a specified number of schema entries
#include <dce/sec_rgy_attr_sch.h>
void sec_rgy_attr_sch_scan(
sec_rgy_handle_t context,
sec_attr_component_name_t schema_name,
sec_attr_cursor_t *cursor,
unsigned32 num_to_read,
unsigned32 *num_read,
sec_attr_schema_entry_t schema_entries[],
error_status_t *status);
Input
- context
An opaque handle bound to a registry server. Use sec_rgy_site_open() to acquire a bound handle.
- schema_name
Reserved for future use.
- num_to_read
An unsigned 32-bit integer specifying the size of the schema_entries[] array and the maximum number of entries to be returned.
Input/Output
- cursor
A pointer to a sec_attr_cursor_t. As input cursor must be allocated and can be initialized. If cursor is not initialized, sec_rgy_attr_sch_scan() will initialize. As output, cursor is positioned at the first schema entry after the returned entries.
Output
- num_read
A pointer an unsigned 32-bit integer specifying the number of entries returned in schema_entries.
- schema_entries[]
A sec_attr_schema_entry_t that contains an array of the returned schema entries.
- status
A pointer to the completion status. On successful completion, the routine returns error_status_ok. Otherwise, it returns an error.
The sec_rgy_attr_sch_scan() routine reads schema entries. The read begins at the entry at which the input cursor is positioned and ends after the number of entries specified in num_to_read.The input cursor must have been allocated by either the sec_rgy_attr_sch_cursor_init() or the sec_rgy_attr_sch_cursor_alloc() call. If the input cursor is not initialized, sec_rgy_attr_sch_scan() initializes it; if cursor is initialized, sec_rgy_attr_sch_scan() simply advances it.
To read all entries in a schema, make successive sec_rgy_attr_sch_scan() calls. When all entries have been read, the call returns the message no_more_entries.
This routine is useful as a browser.
