7.5.11 BSFILE_EXT structure

The BSFILE_EXT structure is a structure to specify two or more output files.
When output file abnormally terminates, the output to two or more files as a recovery processing can be specified when the standard file system of the system is processed.
The size of the area when the area of BSFILE_EXT structure is secured can be calculated by using BS_OUTTABSIZE(n). BS_OUTTABSIZE(n) is a macro to calculate the size of BSFILE_EXT structure with n pieces of information on output file.

Note

When the Btrieve file system is specified for the file system of the input file or the output file, the owner name of the input file or the index information of the output file is specified in the BSFILE_EXT structure.
The output file name is specified for outfile_addr of the BSRTFILE structure.

typedef struct {
    unsigned long            entry_no;
    union {
        BSPTR_BSFILE_BASE    ufs;
        BSPTR_BSFILE_BASE    text;
        BSPTR_BSFILE_BASE    cob;
        BSPTR_BSFILE_BASE    cobr;
        BSPTR_BSFILE_INDEX   cobi;
        BSPTR_BSFILE_INDEX   cisam;
        BSPTR_BSFILE_INDEX   rdm;
        BSPTR_BSFILE_BASE    dosfs;
        BSPTR_BSFILE_BASE    ntfs;
        BSPTR_BSFILE_BTRV    btrieve;
        BSPTR_BSFILE_BASE    sfs;
        BSPTR_BSFILE_BASE    mtfs;

        BSPTR_BSFILE_BASE    mtfi;
    } outfile_opt[1];
} BSFILE_EXT;

BSFILE_EXT structure member

In the following, it explains about the member of the BSFILE_EXT structure.

entry_no

This specifies number of output file path names.
It is considered that the specification of the output file is omitted when 0 is set.

Member that sets file extension information

These members are defined in a union.

outfile_opt[n].ufs
