<xxfdbk.h>

The <xxfdbk.h> include file contains the declarations that are used by the i5/OS® feedback areas. To retrieve information from feedback areas, see _Riofbk() — Obtain I/O Feedback Information and _Ropnfbk() — Obtain Open Feedback Information.

The following is an example of a type that is defined in the <xxfdbk.h> include file:

typedef _Packed struct _XXIOFB_T {
    short       file_dep_fb_offset;
    int         write_count;
    int         read_count;
    int         write_read_count;
    int         other_io_count;
    char        reserved1;
    char        cur_operation;
    char        rec_format[10];
    char        dev_class[2];
    char        dev_name[10];
    int         last_io_rec_len;
    char        reserved2[80];
    short       num_recs_retrieved;
    short       last_io_rec_len2;
    char        reserved3[2];
    int         cur_blk_count;
    char        reserved4[8];
} _XXIOFB_T;
