The ctFRCSNG define forces single entry point calls using the regular API. Enabling this define causes the standard FairCom DB API (i.e., GetRecord(), AddRecord(), . . .) to be routed through the FairCom DB single entry function ctree(). Forcing the single-entry point is used when developing an interface wrapper from another database. This forced single entry point feature is enabled by adding #define ctFRCSNG to ctoptn.h (see the Quick Start and Product Overview Guide for information on modifying ctoptn.h) and requires no modification on the part of the programmer.
