Implemented Interfaces

GInetAddressMask implements GInitable.

Includes

#include <gio/gio.h>

Description

GInetAddressMask represents a range of IPv4 or IPv6 addresses described by a base address and a length indicating how many bits of the base address are relevant for matching purposes. These are often given in string form. Eg, "10.0.0.0/8", or "fe80::/10".

Functions

g_inet_address_mask_new ()

GInetAddressMask *
g_inet_address_mask_new (GInetAddress *addr,
                         guint length,
                         GError **error);

Creates a new GInetAddressMask representing all addresses whose first length bits match addr .

Parameters

addr

a GInetAddress

 

length

number of bits of addr to use

 

error

return location for GError, or NULL

 

Returns

a new GInetAddressMask, or NULL on error

Since: 2.32


g_inet_address_mask_new_from_string ()

GInetAddressMask *
g_inet_address_mask_new_from_string (const gchar *mask_string,
                                     GError **error);

Parses mask_string as an IP address and (optional) length, and creates a new GInetAddressMask. The length, if present, is delimited by a "/". If it is not present, then the length is assumed to be the full length of the address.

Parameters

mask_string

an IP address or address/length string

 

error

return location for GError, or NULL

 

Returns

a new GInetAddressMask corresponding to string , or NULL on error.

Since: 2.32


g_inet_address_mask_to_string ()

gchar *
g_inet_address_mask_to_string (GInetAddressMask *mask);

Converts mask back to its corresponding string form.

Parameters

mask

a GInetAddressMask

 

Returns

a string corresponding to mask .

Since: 2.32


g_inet_address_mask_get_family ()

GSocketFamily
g_inet_address_mask_get_family (GInetAddressMask *mask);

Gets the GSocketFamily of mask 's address

Parameters

mask

a GInetAddressMask

 

Returns

the GSocketFamily of mask 's address

Since: 2.32


g_inet_address_mask_get_address ()

GInetAddress *
g_inet_address_mask_get_address (GInetAddressMask *mask);

Gets mask 's base address

Parameters

mask

a GInetAddressMask

 

Returns

mask 's base address.

[transfer none]

Since: 2.32


g_inet_address_mask_get_length ()

guint
g_inet_address_mask_get_length (GInetAddressMask *mask);

Gets mask 's length

Parameters

mask

a GInetAddressMask

 

Returns

mask 's length

Since: 2.32


g_inet_address_mask_matches ()

gboolean
g_inet_address_mask_matches (GInetAddressMask *mask,
                             GInetAddress *address);

Tests if address falls within the range described by mask .

Parameters

mask

a GInetAddressMask

 

address

a GInetAddress

 

Returns

whether address falls within the range described by mask .

Since: 2.32


g_inet_address_mask_equal ()

gboolean
g_inet_address_mask_equal (GInetAddressMask *mask,
                           GInetAddressMask *mask2);

Tests if mask and mask2 are the same mask.

Parameters

mask

a GInetAddressMask

 

mask2

another GInetAddressMask

 

Returns

whether mask and mask2 are the same mask

Since: 2.32

Types and Values

GInetAddressMask

typedef struct _GInetAddressMask GInetAddressMask;

A combination of an IPv4 or IPv6 base address and a length, representing a range of IP addresses.

Since: 2.32
