#include <db_cxx.h> int DbSequence::stat(DB_SEQUENCE_STAT **spp, u_int32_t flags);
         The DbSequence::stat() method creates a statistical structure and
         copies a pointer to it into user-specified memory locations. 
         Specifically, if spp is non-NULL, a
         pointer to the statistics for the database are copied into the memory
         location to which it refers.
    
Statistical structures are stored in allocated memory. If application-specific allocation routines have been declared (see DbEnv::set_alloc() for more information), they are used to allocate the memory; otherwise, the standard C library malloc(3) is used. The caller is responsible for deallocating the memory. To deallocate the memory, free the memory reference; references inside the returned memory need not be individually freed.
         In the presence of multiple threads or processes accessing an active
         sequence, the information returned by DbSequence::stat() may be
         out-of-date.
    
         The DbSequence::stat() method cannot be transaction-protected.  For
         this reason, it should be called in a thread of control that has no
         open cursors or active transactions.
    
         The DbSequence::stat() 
            
            
                method either returns a non-zero error value or throws an
                exception that encapsulates a non-zero error value on
                failure, and returns 0 on success.
            
        
     
         The statistics are stored in a structure of type DB_SEQUENCE_STAT. 
         The following fields will be filled in:
    
int32_t st_cache_size;
The number of values that will be cached in this handle.
db_seq_t st_current;
The current value of the sequence in the database.
u_int32_t st_flags;
The flags value for the sequence.
db_seq_t st_last_value;
The last cached value of the sequence.
db_seq_t st_min;
The minimum permitted value of the sequence.
db_seq_t st_max;
The maximum permitted value of the sequence.
uintmax_t st_nowait;
The number of times that a thread of control was able to obtain handle mutex without waiting.
db_seq_t st_value;
The current cached value of the sequence.
uintmax_t st_wait;
The number of times a thread of control was forced to wait on the handle mutex.
