File Modes

When c-tree Plus files are created and/or opened, their characteristics are partly determined by the filmod parameter. Some of these modes will be discussed in more detail in later chapters. filmod determines:

• If a file is opened in a standard manner or in a special manner which avoids problems with limited file descriptors;
• If a file is to be shared among multiple users or used exclusively by one user;
• If a data file is comprised of fixed length or variable length records;
• The method of transaction management for the file;
• If a file is to contain Resources;
• If a file is to be a Superfile.
