SuperfilePrepassXtd

Preprocess superfiles to allow rebuilds.

Short Name

CTSBLDX()

Type

Low-Level function

Declaration

COUNT SuperfilePrepassXtd(pTEXT filnam, pTEXT fileword)

Description

SuperfilePrepassXtd() processes the superfile in place. Because a superfile holds numerous c-tree files in one physical file, there are complex inter-file relationships that SuperfilePrepassXtd() function cleans up.

SuperfilePrepassXtd() empties the index files. Each file in the superfile must now be processed by RebuildIFile() before it is usable.

As is the case with RebuildIFile(), the superfile must be closed prior to calling SuperfilePrepassXtd(). Both SuperfilePrepassXtd() and RebuildIFile() open and close the superfile and members.

In single user environments, the fileword parameter, file password, is ignored; i.e., you should pass both parameters, but the second one is ignored.

This operation is available as both a function and stand-alone utility. The function call can be used in single-user and client/server applications. The stand-alone implementation, ctsbld, is available only as a single-user utility.

Return

Value	Symbolic Constant	Explanation
0	NO_ERROR	SuperfilePrepassXtd() completed successfully.
12	FNOP_ERR	Could not open file. Check isam_fil for the specific file number. See c-tree Error Codes for more details.
43	FVER_ERR	Current c-tree configuration is incompatible with file.
46	FUSE_ERR	File number is already in use.
48	FMOD_ERR	Operation is incompatible with the file type.
62	LERR_ERR	Underlying data file must be opened in ctEXCLUSIVE mode.
165	SNFB_ERR	No file control block is available.
418	SNAM_ERR	Name inconsistency.
485		File sortwork.00x could not be created. Increase fils in c-tree initialization.

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

Example

TEXT filnam[64];

printf("\nEnter superfile host name: ");

scanf("%63s",filnam);

if (SuperfilePrepassXtd(filnam, NULL))

printf("\nError on superfile pre-pass, error = %d on file

%d", isam_err, isam_fil);
