sec_rgy_attr_sch_scan(3sec)

Reads a specified number of schema entries

Synopsis

#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);

Parameters

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 initialized. 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.

Description
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.

Permissions Required
The sec_rgy_attr_sch_scan( ) routine requires r permission on the attr_schema object.
