| ## dce_attr_sch_scan(3dce) Reads a specified number of schema entries Synopsis #include <dce/dce_attr_base.h> void dce_attr_sch_scan( dce_attr_sch_handle_t h, dce_attr_cursor_t *cursor, unsigned32 num_to_read, unsigned32 *num_read, dce_attr_schema_entry_t schema_entries[], error_status_t *status); Parameters Input h An opaque handle bound to a schema object. Use dce_attr_sch_bind( ) to acquire the handle. 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 dce_attr_cursor_t. As input cursor must be allocated and can be initialized. If cursor is not initialized, dce_attr_sch_scan will initialize it. As output, cursor is positioned at the first schema entry after the returned entries. Output num_read A pointer to an unsigned 32-bit integer specifying the number of entries returned in schema_entries[]. schema_entries[] A dce_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 dce_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 dce_attr_sch_cursor_init( ) or the dce_attr_sch_cursor_alloc( ) call. If the input cursor is not initialized, dce_attr_sch_scan( ) initializes it; if cursor is initialized, dce_attr_sch_scan( ) simply advances it. To read all entries in a schema, make successive dce_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 dce_attr_sch_scan( ) routine requires appropriate permissions on the schema object. These permissions are managed by the target server.
