I assume that your file has no subgroups.
1. Get the list of variable ids
int status;
int nvars;
int* varids;
/* Get # of variables */
status = nc_inq_varids(ncid, &nvars, NULL);
if(nvars == 0) return status;
varids = malloc(sizeof(int)*nvars);
if(varids == NULL) {status = NC_ENOMEM; return status;}
/* repeat to get the variable ids */
status = nc_inq_varids(ncid, &nvars, varids);
2. Iterate over the variable ids to get the names
int i;
for(i=0;i<nvars;i++) {
char name[NC_MAX_NAME+1];
status = nc_inq_varname(ncid,varids[i],name);
if(status != NC_NOERR) return status;
fprintf("varid=%d varname=%s\n",varids[i],name);
}
