BlobRootGet()

Retrieves data from the root area of a BLOB file.

Syntax

BlobRootGet() --> xBlobData

Return

The function returns the data stored in the root area of a BLOB file. The data type of this data can be determined using Valtype().

Description

BlobRootGet() is used to read the data stored in the root area of a BLOB file. This data must be previously written with BlobRootPut().

When the BLOB file is open in SHARED mode, function BlobRootLock() must be called to avoid conflicts in concurrent file access. This is the only function that places a lock on the root area of a BLOB file.

Note:  the file Blob.ch must be #included for BlobRootGet() to work.
