.Sh DESCRIPTION
These interfaces add content to an sqlite3_str object previously obtained
from sqlite3_str_new().
.Pp
The sqlite3_str_appendf(X,F,...) and sqlite3_str_vappendf(X,F,V)
interfaces uses the built-in printf functionality of
SQLite to append formatted text onto the end of sqlite3_str
object X.
.Pp
The sqlite3_str_append(X,S,N) method appends
exactly N bytes from string S onto the end of the sqlite3_str
object X.
N must be non-negative.
S must contain at least N non-zero bytes of content.
To append a zero-terminated string in its entirety, use the sqlite3_str_appendall()
method instead.
.Pp
The sqlite3_str_appendall(X,S) method appends
the complete content of zero-terminated string S onto the end of sqlite3_str
object X.
.Pp
The sqlite3_str_appendchar(X,N,C) method
appends N copies of the single-byte character C onto the end of sqlite3_str
object X.
This method can be used, for example, to add whitespace indentation.
.Pp
The sqlite3_str_reset(X) method resets the string
under construction inside sqlite3_str object X back to zero
bytes in length.
.Pp
These methods do not return a result code.
If an error occurs, that fact is recorded in the sqlite3_str
object and can be recovered by a subsequent call to sqlite3_str_errcode(X).
