R-05367-01575:[The first argument to the sqlite3_bind_*() routines is always a pointer to the sqlite3_stmt object returned from sqlite3_prepare_v2() or its variants. ]

R-40874-07817:[In those routines that have a fourth argument, its value is the number of bytes in the parameter. To be clear: the value is the number of bytes in the value, not the number of characters. ] R-16566-16123:[If the fourth parameter to sqlite3_bind_text() or sqlite3_bind_text16() is negative, then the length of the string is the number of bytes up to the first zero terminator. ] If the fourth parameter to sqlite3_bind_blob() is negative, then the behavior is undefined. If a non-negative fourth parameter is provided to sqlite3_bind_text() or sqlite3_bind_text16() or sqlite3_bind_text64() then that parameter must be the byte offset where the NUL terminator would occur assuming the string were NUL terminated. If any NUL characters occur at byte offsets less than the value of the fourth parameter then the resulting string value will contain embedded NULs. The result of expressions involving strings with embedded NULs is undefined.
