Creating a UDF Library

Go Up to Compiling and Linking a Function Module

UDF libraries are standard shared libraries that are dynamically loaded by the database at runtime. You can create UDF libraries on any platform–except NetWare–that is supported by InterBase. To use the same set of UDFs with databases running on different platforms, create separate libraries on each platform where the databases reside. UDFs run on the server where the database resides.

Note: A library, in this context, is a shared object that typically has a dll extension on Windows platforms, and an so extension on Solaris and Linux.

The InterBase examples directory contains sample makefiles (makefile.bc and makefile.msc on Windows platforms, makefile on UNIX) that build a UDF function library from udflib.c.
