This README explains the Objected Oriented ( OO ) nature of the code, i.e. naming convention of the subroutine names and variables.1, Since the code is written in pure ANSI C, so encapulation cannot be done   by language feature. In order to write a class object in C, some explicit   convention in naming the object and its associated methods is used.2, All the objects are either Pointers to a struct, a struct or    primitive types.  For instance,        SLOG      is (SLOG_STREAM *),        SLOG_Bbuf is (SLOG_intvlrec_blist_t *),	SLOG_Irec is (SLOG_intvlrec_t *),         SLOG_Varg is (SLOG_vtrarg_t *),	....        SLOG_bebit is SLOG_bebit_t.   3, And the naming convention of the object's associated methods is as follows:   The name of the object will be the first part of the subroutine name.     And the secord part of the subroutine name is the description of the method.   And the object type is either the returned type of the subroutine   or the type of the first dummy argument.  For instance,   the constructor for SLOG_Irec is "SLOG_intvlrec_t *SLOG_Irec_Create( void )"   the destructor for SLOG_Irec is "SLOG_Irec_Free( SLOG_intvlrec_t *irec )"4, Not every type has constructor and destructor.  If there is a constructor,   there must be a destructor like SLOG_Irec_Create() and   SLOG_Irec_Free() pair.5, When there is interaction between 2 objects in a subroutine, the routine   will be listed as method to the object whose internal is exposed   the most inside the routine.  In order word, the object which is   encapsulated the most from the method will be listed as the subject   of the operation.   For example,   int SLOG_Irec_AddVtrArgs(       SLOG_intvlrec_t *irec,                             const SLOG_vtrarg_t   *varg );   the method, SLOG_Irec_AddVtrArgs(), is method for object, SLOG_Irec   which is also (SLOG_intvlrec_t *).   And irec's internal components   are exposed inside SLOG_Irec_AddVtrArgs(), and varg's internals   should be much less exposed ( or unexposed ) than irec inside    SLOG_Irec_AddVtrArgs(), hence varg is considered subject of the method.6, In the code, SLOG_xxxx() are higher level supporting routine than    SLOG_STM_xxxx(), where xxxx does NOT contain "_".  Both of them are   methods for object SLOG, (SLOG_STREAM *).
