Challenge on SAP SNC / RFC communication

Development of a C program which runs on a SLES10 Linux server and uses the SAP NetWeaver RFC SDK to connect to an SAP system on the same host via SNC (SNC is activated on the SAP system). The program should first prompt the user on command line to enter a funtion module name and the import parameters. The output should be the export parameter of the function module. In this case funtion module SUSR_CHECK_LOGON_DATA should be executed. Results we expect: - coding of the program - howto guide for the compilation - executable version - documentation of the program
