FairCom ISAM for C

DELRFILX

Delete ISAM file and associated indexes to the recycle bin.

Type

ISAM function

Declaration

COUNT DELRFILX(FILNO datno)

Description

DELRFILX() deletes the file and indexes referenced by the ISAM data file with file number datno to the recycle bin, if and only if the file and indexes 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 FairCom DB Error Codes for a complete listing of valid FairCom DB error values.

Example

FILNO datno = 5;

TEXT filnam[15];

printf("\nEnter file name to delete:")

scanf("%14s", filnam);

if (OpenFileWithResource(datno, filnam, ctEXCLUSIVE))

printf("\nCould not open data file or index, error = %d,

file = %d",isam_err,isam_fil);

else if (DELRFILX(datno))

printf("\nCould not delete data file or index, error = %d,

file = %d",isam_err,isam_fil);

Limitations

DELRFILX() calls the Low-Level DELFILX() function, which first closes the file before deletion.

In a non-server model, 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).
