Delete ISAM file and associated indices.

Short Name

DELIFIL()

Type

ISAM function

Declaration

COUNT DeleteIFile(pIFIL ifilptr)

Description

DeleteIFile() deletes the file and indices referenced by the incremental ISAM structure pointed to by ifilptr if and only if the file and indices have been opened in exclusive mode.

Return

Value

Symbolic Constant

Explanation

0

NO_ERROR

Successful file deletion.

55

DLTF_ERR

File could not be deleted. Does any process have the file open?

56

DLTP_ERR

File is not opened in the ctEXCLUSIVE mode. Delete is not performed.

See c-tree Plus Error Codes for a complete listing of valid c-tree Plus error values.

Example

pIFIL   ifilptr;

if (OpenIFile(ifilptr)
     printf("\nCould not open data file or index, error = %d,
            file = %d",isam_err,isam_fil);
else if (DeleteIFile(ifilptr)
     printf("\nCould not delete data file or index, error = %d,
            file = %d",isam_err,isam_fil);

Limitations

DeleteIFile() calls the low-level DeleteCtFile() function, which first closes the file before deletion.

This permits another process to have a small window of opportunity to gain control of the file in which case the delete will fail and result in an error DLTF_ERR (55).
