int SQCloudBlobBytes (SQCloudBlob *blob);


This function returns the size in bytes of the BLOB accessible via the successfully opened BLOB handle in its only argument. The incremental blob I/O routines can only read or overwriting existing blob content; they cannot change the size of a blob.

This function resembles the sqlite3_blob_bytes SQLite API.


Return value

An int value with the size in bytes of the BLOB.

        return -1;
    } else {
        printf("Connection to host OK...\n\n");

    // choose a database first
    SQCloudResult *r = SQCloudExec(conn, "USE DATABASE mydatabase.sqlite;");

    // open a BLOB for reading
    SQCloudBlobOpen *blob = SQCloudBlobOpen(conn, NULL, "mytable", "mycolumn", 1, 0);
