There is an API in CD, it is ndmapi_connect_c(ERROR_H error, char * ndm_hostname, char * ndm_portname). But we need a new version of this API. It is like this: ndmapi_connect_c(ERROR_H error, char * ndm_hostname, char * ndm_portname, char *user_name, char * password). Sometimes, we need just one user to execute the program that calls the connection API, but we hope that this user can change to other CD users to execute tasks. we think that this is userful. Could you supply a new version of ndmapi_connect_c with user and password arguments to us?
