/*
Changes:
2001-05-31: Jeremy Bettis <jeremy@deadbeef.com>
- If a blob handle was expected and something else was
received create a blob and add the value to it.
- If the incoming argument to a bind parameter is NULL
then store a NULL in the database.
- More verbose date errors.
1999-09-21: Ivo Panacek <ivop@regionet.cz>
- added COMPILE_DL section
- more verbose php_info_ibase function
mostly stolen from pgsql.c for now
1999-10-05: Ivo Panacek <ivop@regionet.cz>
- safe rinit/rfinish: check for NULL so
rfinish could be called repeatedly
emalloc & co. replaced with malloc & co.
