One small trap to getdelim()/getline() is that the caller needs to free
lineptr, even if it NULL when called and the call failed, ala:
char *buf = NULL;
size_t len = 0;
ssize_t ret;
ret = getline(&buf, &len, fp);
if (ret == -1) {
free(buf);
return or do whatever...
}
Does this make that clear in the manpage?
