.Sh DESCRIPTION
These interfaces return the current status of an sqlite3_str
object.
.Pp
If any prior errors have occurred while constructing the dynamic string
in sqlite3_str X, then the sqlite3_str_errcode(X)
method will return an appropriate error code.
The sqlite3_str_errcode(X) method returns SQLITE_NOMEM
following any out-of-memory error, or SQLITE_TOOBIG if
the size of the dynamic string exceeds SQLITE_MAX_LENGTH,
or SQLITE_OK if there have been no errors.
.Pp
The sqlite3_str_length(X) method returns the current
length, in bytes, of the dynamic string under construction in sqlite3_str
object X.
The length returned by sqlite3_str_length(X) does
not include the zero-termination byte.
.Pp
The sqlite3_str_value(X) method returns a pointer
to the current content of the dynamic string under construction in
X.
The value returned by sqlite3_str_value(X) is managed
by the sqlite3_str object X and might be freed or altered by any subsequent
method on the same sqlite3_str object.
Applications must not used the pointer returned sqlite3_str_value(X)
after any subsequent method call on the same object.
Applications may change the content of the string returned by sqlite3_str_value(X)
as long as they do not write into any bytes outside the range of 0
to sqlite3_str_length(X) and do not read or write
any byte after any subsequent sqlite3_str method call.
