#include <sys/types.h> #include "lfc_api.h" int lfc_getusrmap (int *nbentries, struct lfc_userinfo **usr_entries)
lfc_getusrmap gets all the existing users from the virtual uid table. nbentries will be set to the number of entries in the array of user infos. usr_entries will be set to the address of an array of lfc_userinfo structures allocated by the API.
