dpns_modifygrpmap - modify group entry corresponding to a given virtual gid
#include <sys/types.h> #include "dpns_api.h" int dpns_modifygrpmap (gid_t gid, char *newname, int status)
dpns_modifygrpmap modifies the group entry corresponding to a given virtual gid. gid specifies the Virtual Group Id. newname specifies the new group name. It must be at most 255 characters long. status status can be set to 0 or a combination of ARGUS_BAN and LOCAL_BAN. This function requires ADMIN privilege.

EACCES The caller does not have ADMIN privilege. EFAULT newname is a NULL pointer. EEXIST This group exists already. EINVAL This gid does not exist in the internal mapping table or the length of newname exceeds 255. SENOSHOST Host unknown. SENOSSERV Service unknown. SECOMERR Communication error.
