Hi, I am trying to implement a user-defined function (not aggregate function) that takes two arguments.
SQLite version is 3.8.11.1 - (1) According to the paragraph near the bottom of this help page (https://www.sqlite.org/c3ref/value_blob.html) >> Please pay particular attention to the fact that the pointer returned from >> sqlite3_value_blob(), sqlite3_value_text(), or sqlite3_value_text16() can be >> invalidated by a subsequent call to sqlite3_value_bytes(), >> sqlite3_value_bytes16(), sqlite3_value_text(), or sqlite3_value_text16(). If I get a pointer to the first argument via sqlite3_value_text16(), and call it AGAIN to get a pointer to the second argument, does it mean the first pointer will be invalidated? (2) Is there a built-in cleanup functions that I have to call for these pointers? Thanks. David Lee.
