The following typographical conventions are used within in this manual:

Class names are represented in monospaced font, as are method names. For example: "DbEnv::open() is a DbEnv class method."

Variable or non-literal text is presented in italics. For example: "Go to your DB_INSTALL directory."

Program examples are displayed in a monospaced font on a shaded background. For example:

typedef struct vendor {
    char name[MAXFIELD];             // Vendor name
    char street[MAXFIELD];           // Street name and number
    char city[MAXFIELD];             // City
    char state[3];                   // Two-digit US state code
    char zipcode[6];                 // US zipcode
    char phone_number[13];           // Vendor phone number
} VENDOR; 

In some situations, programming examples are updated from one chapter to the next. When this occurs, the new code is presented in monospaced bold font. For example:

typedef struct vendor {
    char name[MAXFIELD];             // Vendor name
    char street[MAXFIELD];           // Street name and number
    char city[MAXFIELD];             // City
    char state[3];                   // Two-digit US state code
    char zipcode[6];                 // US zipcode
    char phone_number[13];           // Vendor phone number
    char sales_rep[MAXFIELD];        // Name of sales representative
    char sales_rep_phone[MAXFIELD];  // Sales rep's phone number 
} VENDOR;
