| The |

| .BR telldir (3). |
| .SH RETURN VALUE |

| .SH NOTES |
| In glibc up to version 2.1.1, the type of the |
| .I loc |
| argument was |
| .IR off_t . |
| POSIX.1-2001 specifies |
| .IR long , |
| and this is the type used since glibc 2.1.2. |
| See |
| .BR telldir (3) |
| for information on why you should be careful in making any |
| assumptions about the value in this argument. |
