GcrComparable

GcrComparable — Interface for comparing objects

Types and Values

Object Hierarchy

    GInterface
    ╰── GcrComparable

Prerequisites

GcrComparable requires GObject.

Known Derived Interfaces

GcrComparable is required by GcrCertificate.

Known Implementations

GcrComparable 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.

[allow-none]

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.

[skip]

Parameters

mem1

First block of memory.

[array length=size1][element-type guint8]

size1

Length of first block

 

mem2

Second block of memory.

[array length=size2][element-type guint8]

size2

Length of second block

 

Returns

Zero if the blocks are identical, negative if first less than secend, possitive otherwise.

Types and Values

GcrComparable

typedef struct _GcrComparable GcrComparable;

The GcrComparable interface is implemented by comparable objects.


struct GcrComparableIface

struct GcrComparableIface {
	GTypeInterface parent;
	gint (*compare) (GcrComparable *self, GcrComparable *other);
};

The interface to implement for GcrComparable

Members

GTypeInterface parent;

type interface

 

compare ()

Compare whether tow objects represent the same thing.
