| |
|
virtual |
Calculate a new checksum for a physical file using the checksum algorithm named in the Cks parameter.
- Parameters
-
Xfn | The logical or physical name of the file to be checksumed. |
Cks | For input, it specifies the checksum algorithm to be used. For output, the checksum value is returned upon success. |
doSet | When true, the new value must replace any existing value in the Xfn's extended file attributes. |
pcbP | In the second form, the pointer to the callback object. A nil pointer does not invoke any callback. |
- Returns
- Success: zero with Cks structure holding the checksum value. Failure: -errno (see significant error numbers below).

( |

| |
|
virtual |
Delete the checksum from the Xfn's xattrs.
- Parameters
-
Xfn | The logical or physical name of the file to be checksumed. |
Cks | Specifies the checksum type to delete. |
- Returns
- Success: 0 Failure: -errno (see significant error numbers below).

| |
|
virtual |
Retreive the checksum from the Xfn's xattrs and return it and indicate whether or not it is stale (i.e. the file modification has changed or the name and length are not the expected values).
- Parameters
-
Xfn | The logical or physical name of the file to be checksumed. |
Cks | For input, it specifies the checksum type to return. For output, the checksum value is returned upon success. |
- Returns
- Success: The length of the binary checksum in the Cks structure. Failure: -errno (see significant error numbers below).

) |
| |
|
virtual |
List names of the checksums associated with a Xfn or all supported ones.
- Parameters
-
Xfn | The logical or physical file name whose checksum names are to be returned. When Xfn is null, return all supported checksum algorithm names. |
Buff | Points to a buffer, at least 64 bytes in length, to hold a "Sep" separated list of checksum names. |
Blen | The length of the buffer. |
Sep | The separation character to be used between adjacent names. |
- Returns
- Success: Pointer to Buff holding at least one checksum name. Failure: A nil pointer is returned.

|
) |
| |
|
virtual |
Set a file's checksum in the extended attributes along with the file's mtime and the time of setting.
- Parameters
-
Xfn | The logical or physical name of the file to be set. |
Cks | Specifies the checksum name and value. |
myTime | When true then the fmTime and gmTime in the Cks structure are to be used; as opposed to the current time. |
- Returns
- Success: zero is returned. Failure: -errno (see significant error numbers below).

( |
const char * |
Xfn, |

|
XrdCksData & |
Cks |
|
) |
| |
|
virtual |
Retreive the checksum from the Xfn's xattrs and compare it to the supplied checksum. If the checksum is not available or is stale, a new checksum is calculated and written to the extended attributes.
- Parameters
-
Xfn | The logical or physical name of the file to be verified. |
Cks | Specifies the checksum name and value. |
pcbP | In the second form, the pointer to the callback object. A nil pointer does not invoke any callback. |
- Returns
- Success: True Failure: False (the checksums do not match) or -errno indicating that verification could not be performed (see significant error numbers below).
