Hi,
We're having a problem with registering RFC functions to a SAP RFC Gateway.
When using a given program, roughly based on the "rfcthsrv.c" example, in
which we install a given function towards the SAP RFC Gateway,
then call RfcAccept and finally, after a short time, check if the function
was installed correctly.
This train of events works fine when used on one system (hostname: PC_JALA),
but it does not work correctly when used on another system
(hostname: PC_SIS_SAP).
The call to RfcInstallFunction returns RFC_OK, but checking with
RfcCheckRegisterServer later on results in a total of 0 installed functions.
This seems to be an inconsistency in the SAP RFC interface.
We're using "SAP Frontend Package 6.20 Final Compilation 3".
