Functions¶

const char * keyOwner (const Key *key)

Return a pointer to the real internal key owner. " ssize_t keyGetOwnerSize (const Key *key)

Return the size of the owner of the Key with concluding 0. " ssize_t keyGetOwner (const Key *key, char *returnedOwner, size_t maxSize)
Return the owner of the key. ssize_t keySetOwner (Key *key, const char *newOwner)
Set the owner of a key.

ssize_t keyGetOwner (const Key * key, char * returnedOwner, size_t maxSize)¶

Return the owner of the key.

• Given user:someuser/..... return someuser
• Given user:some.user/.... return some.user
• Given user/.... return the current user

Only user/... keys have a owner. For system/... keys (that doesn't have a key owner) an empty string ('') is returned.

Although usually the same, the owner of a key is not related to its UID. Owner are related to WHERE the key is stored on disk, while UIDs are related to mode controls of a key.

Parameters:

Returns:

ssize_t keyGetOwnerSize (const Key * key)¶

Return the size of the owner of the Key with concluding 0. The returned number can be used to allocate a string. 1 will returned on an empty owner to store the concluding 0 on using keyGetOwner().

char * buffer;
buffer = elektraMalloc (keyGetOwnerSize (key));
// use buffer and keyGetOwnerSize (key) for maxSize

Note:

Parameters:

const char* keyOwner (const Key * key)¶

Return a pointer to the real internal key owner. This is a much more efficient version of keyGetOwner() and you should use it if you are responsible enough to not mess up things. You are not allowed to modify the returned string in any way. If you need a copy of the string, consider to use keyGetOwner() instead.

keyOwner() returns '' when there is no keyOwner. The reason is

key=keyNew(0);
keySetOwner(key,"");
keyOwner(key); // you would expect "" here
keySetOwner(key,"system");
keyOwner(key); // you would expect "" here

Note:

Parameters:

Returns:

Return values:

ssize_t keySetOwner (Key * key, const char * newOwner)¶

Set the owner of a key. A owner is a name of a system user related to a UID. The owner decides on which location on the disc the key goes.

A private copy is stored, so the passed parameter can be freed after the call.

Parameters:

Returns:
