.Sh DESCRIPTION
The
.Li krb5_ccache
structure holds a Kerberos credential cache.
.Pp
The
.Li krb5_cc_cursor
structure holds current position in a credential cache when
iterating over the cache.
.Pp
The
.Li krb5_cc_ops
structure holds a set of operations that can me preformed on a
credential cache.
.Pp
There is no component inside
.Li krb5_ccache ,
.Li krb5_cc_cursor
nor
.Li krb5_fcc_ops
that is directly referable.
.Pp
The
.Li krb5_creds
holds a Kerberos credential, see manpage for
.Xr krb5_creds 3 .
.Pp
.Fn krb5_cc_default_name
and
.Fn krb5_cc_set_default_name
gets and sets the default name for the
.Fa context .
.Pp
.Fn krb5_cc_default
opens the default ccache in 
.Fa id .
Return 0 or an error code.
.Pp
.Fn krb5_cc_gen_new
generates a new ccache of type
.Fa ops
in
.Fa id .
Return 0 or an error code.
.Pp
.Fn krb5_cc_resolve
finds and allocates a ccache in 
.Fa id
from the specification in 
.Fa residual .
If the ccache name doesn't contain any colon (:), interpret it as a
file name.
Return 0 or an error code.
.Pp
.Fn krb5_cc_initialize
creates a new ccache in
.Fa id
for
.Fa primary_principal .
Return 0 or an error code.
.Pp
.Fn krb5_cc_close
stops using the ccache 
.Fa id
and frees the related resources.
Return 0 or an error code.
.Fn krb5_cc_destroy
removes the ccache 
and closes (by calling
.Fn krb5_cc_close )
.Fa id .
Return 0 or an error code.
.Pp
.Fn krb5_cc_copy_cache
copys the contents of 
.Fa from
to 
.Fa to .
.Pp
.Fn krb5_cc_get_name
returns the name of the ccache 
.Fa id .
.Pp
.Fn krb5_cc_get_principal
returns the principal of 
.Fa id
in
.Fa principal .
Return 0 or an error code.
.Pp
.Fn krb5_cc_get_type
returns the type of the ccache
.Fa id .
.Pp
.Fn krb5_cc_get_ops
returns the ops of the ccache
.Fa id .
.Pp
.Fn krb5_cc_get_version
returns the version of
.Fa id .
.Pp
.Fn krb5_cc_register
Adds a new ccache type with operations 
.Fa ops ,
overwriting any existing one if
.Fa override .
Return an error code or 0.
.Pp
.Fn krb5_cc_remove_cred
removes the credential identified by
.Fa ( cred ,
.Fa which )
from 
.Fa id .
.Pp
.Fn krb5_cc_store_cred
stores
.Fa creds
in the ccache
.Fa id .
Return 0 or an error code.
.Pp
.Fn krb5_cc_set_flags
sets the flags of
.Fa id
to
.Fa flags .
.Pp
.Fn krb5_cc_retrieve_cred ,
retrieves the credential identified by 
.Fa mcreds
(and
.Fa whichfields )
from
.Fa id
in
.Fa creds .
Return 0 or an error code.
.Pp
.Fn krb5_cc_next_cred
retrieves the next cred pointed to by
.Fa ( id ,
.Fa cursor )
in
.Fa creds ,
and advance
.Fa cursor .
Return 0 or an error code.
.Pp
.Fn krb5_cc_end_seq_get
Destroys the cursor
.Fa cursor .
