Do you mean a C function on the server side or on the client side? For examples of server-side code, take a look at functions in the PostgreSQL source that handle BYTEA, e.g., byteacat() in src/backend/utils/adt/varlena.c. See also the comments concerning variable-length data and the relevant examples in the "C-Language Functions" section of the "Extending SQL" chapter in the documentation. -- Michael Fuhr http://www.fuhr.org/~mfuhr/ ---------------------------(end of broadcast)--------------------------- TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED]
