These interfaces add content to an sqlite3_str object previously obtained from sqlite3_str_new().
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.
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.
The sqlite3_str_appendall(X,S) method appends the complete content of zero-terminated string S onto the end of sqlite3_str object X.
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.
The sqlite3_str_reset(X) method resets the string under construction inside sqlite3_str object X back to zero bytes in length.
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).
