SAPRFC Version 1.3.3 released
added official support for installation saprfc as dynamic module, because compilation saprfc failed under new Linux distribution (for example RH AS 3.0, Fedora Core 3) - reason: librfc.a library from SAP RFCSDK 6.20 is not compatible with glibc 2.3.

SAPRFC Version 1.3.2 released

SAPRFC Version 1.2.1 released

SAPRFC Version 1.2 released
- fixed API function saprfc_exception(). This function is public and works now...

SAPRFC Version 1.1 released
Determination of offset position for structure fields in the internal buffer was changed. Instead of computation from field data type and it position in the structure, is offset set from OFFSET value returned by RFC_GET_FUNCTION_INTERFACE_P (in the saprfc_function_discover()). This change solve data corruption problem for parameters or tables that has structure that includes other structure, e.g. like table MARA. The API for function saprfc_function_define() and saprfc_function_interface() was a little changed, but it's backward compatible. The item "offset" was added to the field definition. If this item is not set, old method for offset determination is used.
