Samisa Abeysinghe commented on AXISCPP-287:
-------------------------------------------

It is an excellent idea to validate shared libs loaded.

Could we achieve this by having the DLLs contain a class that extends a base class, say SharedLib with a virtual method:
void getVersion( char * pcLibType, char * pcVersion )

We may also define a global set of values for Lib Types such as:
"Transport Lib", "XML Parser Lib", "Secure Channel", etc.

This has lead to unexpected behaviour when the XMLParser directory path was inadvertently swapped with Transport.  By adding an exported method to the DLL (i.e void GetVersion( char * pszBuildInfo, char * pszDLLType)), the DLL loader could verify that the DLL it has just loaded was of the expected type.
