| .SH "DESCRIPTION" |
| .BR selabel_lookup () |
| performs a lookup operation on the handle |
| .IR hnd , |
| returning the result in the memory pointed to by |
| .IR context , |
| which must be freed by the caller using |
| .BR freecon (3). |
| The |
| .I key |
| and |
| .I type |
| parameters are the inputs to the lookup operation and are interpreted according to the specific backend that |
| .I handle |
| is open on. |
| |
| .BR selabel_lookup_raw () |
| behaves identically to |
| .BR selabel_lookup () |
| but does not perform context translation. |
| . |
| .SH "RETURN VALUE" |
| On success, zero is returned. On error, \-1 is returned and |
| .I errno |
| is set appropriately. |
| . |
| .SH "ERRORS" |
| .TP |
| .B ENOENT |
| No context corresponding to the input |
| .I key |
| and |
| .I type |
| was found. |
| .TP |
| .B EINVAL |
| The |
| .I key |
| and/or |
| .I type |
| inputs are invalid, or the context being returned failed validation. |
| .TP |
| .B ENOMEM |
| An attempt to allocate memory failed. |
