PolKitError

typedef struct _PolKitError PolKitError;

Objects of this class are used for error reporting.


polkit_error_is_set ()

polkit_bool_t       polkit_error_is_set                 (PolKitError *error);

Determine if an error set

error :

the error

Returns :

TRUE if, and only if, the error is set

Since 0.7


polkit_error_get_error_name ()

const char *        polkit_error_get_error_name         (PolKitError *error);

Get the CamelCase name for the error; e.g. POLKIT_ERROR_OUT_OF_MEMORY maps to "OutOfMemory" and so on.

error :

the error

Returns :

the string

Since 0.7


polkit_error_get_error_code ()

PolKitErrorCode     polkit_error_get_error_code         (PolKitError *error);

Returns the error code.

error :

the error object

Returns :

A value from the PolKitErrorCode enumeration.

polkit_error_get_error_message ()

const char *        polkit_error_get_error_message      (PolKitError *error);

Get the error message.

error :

the error object

Returns :

A string describing the error. Caller shall not free this string.

polkit_error_free ()

void                polkit_error_free                   (PolKitError *error);

Free an error.

error :

the error

polkit_error_set_error ()

polkit_bool_t       polkit_error_set_error              (PolKitError **error,
                                                         PolKitErrorCode error_code,
                                                         const char *format,

Sets an error. If OOM, the error will be set to a pre-allocated OOM error.

error :

error_code :

A value from the PolKitErrorCode enumeration.

format :
