Prerequisites

GcrComparableIface requires GObject.

Known Derived Interfaces

GcrComparableIface is required by GcrCertificate.

Known Implementations

GcrComparableIface is implemented by GcrCertificateRenderer, GcrPkcs11Certificate and GcrSimpleCertificate.

Description

The GcrComparable interface is implemented by objects when they should be comparable against one another.

Functions

gcr_comparable_compare ()

gint
gcr_comparable_compare (GcrComparable *self,
                        GcrComparable *other);

Compare whether two objects represent the same thing. The return value can also be used to sort the objects.

Parameters

self

The comparable object

 

other

Another comparable object

 

Returns

Zero if the two objects represent the same thing, non-zero if not.


gcr_comparable_memcmp ()

gint
gcr_comparable_memcmp (gconstpointer mem1,
                       gsize size1,
                       gconstpointer mem2,
                       gsize size2);

Compare two blocks of memory. The return value can be used to sort the blocks of memory.

Parameters

mem1

First block of memory

 

size1

Length of first block

 

mem2

Second lock of memory

 

size2

Length of second block

 

Returns

Zero if the blocks are identical, non-zero if not.

Types and Values
