Types and Values

enum GckError
#define GCK_INVALID

Description

A few supporting functions that come in handy when dealing with the gck library or PKCS11 in general.

Functions

gck_list_ref_copy ()

GList *
gck_list_ref_copy (GList *reflist);

Copy a list of GObject based pointers. All objects in the list will be reffed and the list will be copied.

[skip]

Parameters

reflist

list of GObject reference counted objects.

[element-type GObject.Object]

Returns

the copied and reffed list, when done, free it with gck_list_unref_free().

[transfer full][element-type GObject.Object]


gck_list_unref_free ()

void
gck_list_unref_free (GList *reflist);

Free a list of GObject based pointers. All objects in the list will be unreffed and then the list itself will be freed.

[skip]

Parameters

reflist

list of Gobject reference counted pointers.

[element-type GObject.Object]

gck_string_from_chars ()

gchar *
gck_string_from_chars (const guchar *data,
                       gsize max);

Create a string from a set of PKCS#11 characters. This is similar to g_strndup, except for that it also strips trailing spaces. These space padded strings are often used in PKCS#11 structures.

If the space padded string is filled with null characters then this function will return NULL.

[skip]

Parameters

data

The character data to turn into a null terminated string.

 

max

The maximum length of the charater data.

 

Returns

The null terminated string.


gck_string_to_chars ()

gboolean
gck_string_to_chars (guchar *data,
                     gsize max,
                     const gchar *string);

Create a space padded PKCS#11 string from a null terminated string. The string must be shorter than the buffer or FALSE will be returned.

If a NULL string is passed, then the space padded string will be set to zero characters.

[skip]

Parameters

data

The character buffer to place string into.

 

max

The maximum length of the charater buffer.

 

string

The string to place in the buffer.

 

Returns

The null terminated string.


gck_value_to_boolean ()

gboolean
gck_value_to_boolean (const guchar *value,
                      gsize length,
                      gboolean *result);

Convert CK_BBOOL type memory to a boolean.

Parameters

value

memory to convert.

[array length=length]

length

length of memory

 

result

A location to store the result

 

Returns

Whether the conversion was successful.


gck_value_to_ulong ()

gboolean
gck_value_to_ulong (const guchar *value,
                    gsize length,
                    gulong *result);

Convert CK_ULONG type memory to a boolean.

Parameters

value

memory to convert.

[array length=length]

length

length of memory

 

result

A location to store the result

 

Returns

Whether the conversion was successful.

Types and Values

enum GckError

Various error codes. All the CKR_XXX error codes from PKCS#11 are also relevant error codes.

Members

GCK_ERROR_MODULE_PROBLEM

a result code that signifies there was a problem loading a PKCS#11 module, usually a shared library

 

GCK_INVALID

#define GCK_INVALID ((gulong)-1)

Used as a terminator at the end of variable argument lists.
