.Sh DESCRIPTION
|
|
The
|
|
.Li krb5_data
|
|
structure holds a data element.
|
|
The structure contains two public accessible elements
|
|
.Fa length
|
|
(the length of data)
|
|
and
|
|
.Fa data
|
|
(the data itself).
|
|
The structure must always be initiated and freed by the functions
|
|
documented in this manual.
|
|
.Pp
|
|
.Fn krb5_data_zero
|
|
resets the content of
|
|
.Fa p .
|
|
.Pp
|
|
.Fn krb5_data_free
|
|
free the data in
|
|
.Fa p
|
|
and reset the content of the structure with
|
|
.Fn krb5_data_zero .
|
|
.Pp
|
|
.Fn krb5_free_data_contents
|
|
works the same way as
|
|
.Fa krb5_data_free .
|
|
The diffrence is that krb5_free_data_contents is more portable (exists
|
|
in MIT api).
|
|
.Pp
|
|
.Fn krb5_free_data
|
|
frees the data in
|
|
.Fa p
|
|
and
|
|
.Fa p
|
|
itself.
|
|
.Pp
|
|
.Fn krb5_data_alloc
|
|
allocates
|
|
.Fa len
|
|
bytes in
|
|
.Fa p .
|
|
Returns 0 or an error.
|
|
.Pp
|
|
.Fn krb5_data_realloc
|
|
reallocates the length of
|
|
.Fa p
|
|
to the length in
|
|
.Fa len .
|
|
Returns 0 or an error.
|
|
.Pp
|
|
.Fn krb5_data_copy
|
|
copies the
|
|
.Fa data
|
|
that have the length
|
|
.Fa len
|
|
into
|
|
.Fa p .
|
|
.Fa p
|
|
is not freed so the calling function should make sure the
|
|
.Fa p
|
|
doesn't contain anything needs to be freed.
|
|
Returns 0 or an error.
|
|
.Pp
|
|
.Fn krb5_copy_data
|
|
copies the
|
|
.Li krb5_data
|
|
in
|
|
.Fa indata
|
|
to
|
|
.Fa outdata .
|
|
.Fa outdata
|
|
is not freed so the calling function should make sure the
|
|
.Fa outdata
|
|
doesn't contain anything needs to be freed.
|
|
.Fa outdata
|
|
should be freed using
|
|
.Fn krb5_free_data .
|
|
Returns 0 or an error.
|
|
.Pp
|
|
.Fn krb5_data_cmp
|
|
will compare two data object and check if they are the same in a
|
|
simular way as memcmp does it. The return value can be used for
|
|
sorting.
