dpns_entergrpmap - define a new group entry in Virtual Id table
#include <sys/types.h> #include "dpns_api.h" int dpns_entergrpmap (gid_t gid, char *groupname)

EACCES The caller does not have ADMIN privilege. EFAULT groupname is a NULL pointer. EEXIST Group exists already. EINVAL The length of groupname exceeds 255. SENOSHOST Host unknown. SENOSSERV Service unknown. SECOMERR Communication error. ENSNACT Name server is not running or is being shutdown.
