Hi, I have a weird problem with my custom functions (written in C,C++) that use bytea as input type (cstring works fine). The functions will work as expected if they are the only function that uses the bytea column in a query; as soon as there is a second function using the same column, the C function will return one of the following: an empty cstring, a substring of the bytea or the correct cstring. Based on these symptoms I assume there is something fundamental that I do wrong (or that is missing) with handling the bytea pointer.
In one specific example, the bytea contains a binary file format that the function converts into a string format. I convert the bytea to a C++ string with string(VARDATA(b), VARSIZE(b)-VARHDRSZ). bytea *b = PG_GETARG_BYTEA_P(0); char *ism; ism = function(b); PG_RETURN_CSTRING(ism); -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
