Detailed Description

A JSON value representation capable of holding one of the seven types above. For "string", "number", "object", and "array" additional data is available in the union. The "OYJL_IS_*" and "OYJL_GET_*" macros below allow type checking and convenient value extraction.

Examples:

tutorial_json_options.c.

d

double oyjl_val_s::d

double value, if representable.

flags

unsigned int oyjl_val_s::flags

Signals whether the i and d members are valid. See OYJL_NUMBER_INT_VALID and OYJL_NUMBER_DOUBLE_VALID.

i

long long oyjl_val_s::i

integer value, if representable.

keys

char** oyjl_val_s::keys

Array of keys.

len

size_t oyjl_val_s::len

Number of key-value-pairs.

Number of elements.

type

oyjl_type oyjl_val_s::type

u

union { ... } oyjl_val_s::u

Type-specific data. You may use the "OYJL_GET_*" macros to access these members.
