Check a value type in bits is correct and as expected.
lyplg_lyb_size_type
Type of the LYB size of a value of a particular type.
YANG extension compiled instance.
LY_ERR
libyang's error codes returned by the libyang functions.
uint8_t ly_bool
Type to indicate boolean value.
#define LYPLG_TYPE_STORE_DYNAMIC
#define LYPLG_IPV6PREF_LYB_VALUE_SIZE
LYPLG_TYPE_VAL_INLINE_DESTROY(val)
The main libyang public header.
YANG data representation.
Libyang full error structure.
#define LYD_VALUE_GET(value, type_val)
Get the value in format specific to the type.
LIBYANG_API_DECL LY_ERR ly_err_new(struct ly_err_item **err, LY_ERR ecode, LY_VECODE vecode, char *data_path, char *apptag, const char *err_format,...) _FORMAT_PRINTF(6

struct lyplg_type_record plugins_ipv6_prefix[]
Plugin information for ipv6-prefix type implementation.
#define LYPLG_TYPE_VAL_IS_DYN(type_val)
Check whether specific type value needs to be allocated dynamically.
Special lyd_value structure for ietf-inet-types ipv6-prefix values.
LIBYANG_API_DECL LY_ERR lydict_insert_zc(const struct ly_ctx *ctx, char *value, const char **str_p)
Insert string into dictionary - zerocopy version. If the string is already present, only a reference counter is incremented and no memory allocation is performed. This insert function variant avoids duplication of specified value - it is inserted into the dictionary directly.
LY_VALUE_FORMAT
All kinds of supported value formats and prefix mappings to modules.
#define LYPLG_TYPE_VAL_INLINE_PREPARE(storage, type_val)
Prepare value memory for storing a specific type value, may be allocated dynamically.
return memcmp(v1->data, v2->data, bitmap_size)
LIBYANG_API_DECL LY_ERR lyplg_type_check_hints(uint32_t hints, const char *value, uint32_t value_len, LY_DATA_TYPE type, int *base, struct ly_err_item **err)
Check that the type is suitable for the parser's hints (if any) in the specified format.
