GWEN_DBIO* GWEN_DBIO_GetPlugin | ( | const char * | modname | ) |
This function creates a GWEN_DBIO of the given name. It therefore loads the appropriate plugin if necessary. The caller becomes the owner of the object returned, so he/she is responsible for freeing it (Note: Previous version kept the ownership so that the caller was not allowed to free the object. This has changed).
