If the provided buffer length was too small, this function returns an error condition of CborErrorOutOfMemory. If you need to calculate the length of the string in order to preallocate a buffer, use cbor_value_calculate_string_length().
│ │ │
On success, this function sets the number of bytes copied to *buflen. If the buffer is large enough, this function will insert a null byte after the last copied byte, to facilitate manipulation of null-terminated strings. That byte is not included in the returned value of *buflen.
│ │ │
The next pointer, if not null, will be updated to point to the next item after this string. If value points to the last item, then next will be invalid.
│ │ │
This function may not run in constant time (it will run in O(n) time on the number of chunks). It requires constant memory (O(1)).

On success, this function sets the number of bytes copied to *buflen. If the buffer is large enough, this function will insert a null byte after the last copied byte, to facilitate manipulation of text strings. That byte is not included in the returned value of *buflen. If there was no space for the terminating null, no error is returned, so callers must check the value of *buflen after the call, before relying on the '\0'; if it has not been changed by the call, there is no '\0'-termination on the buffer's contents.

Note
This function does not perform UTF-8 validation on the incoming text string.
Retrieves the CBOR half-precision floating point (16-bit) value that value points to and stores it in result.
│ │ │
If the iterator value does not point to a half-precision floating point value, the behavior is undefined, so checking with cbor_value_get_type or with cbor_value_is_half_float is recommended.
│ │ │
Note: since the C language does not have a standard type for half-precision floating point, this function takes a void * as a parameter for the storage area, which must be at least 16 bits wide.
The next pointer, if not null, will be updated to point to the next item after this string. During iteration, the pointer must only be passed back again to this function; passing it to any other function in this library results in undefined behavior. If there are no more chunks to be read from value, then next will be set to the next item after this string; if value points to the last item, then next will be invalid.

Converts the current CBOR type pointed by value to its textual representation and writes it to the stream by calling the streamFunction.
│ │ │
If an error occurs, this function returns an error code similar to Parsing CBOR streams.
│ │ │
The textual representation can be controlled by the flags parameter (see CborPrettyFlags for more information).
│ │ │
If no error ocurred, this function advances value to the next element. Often, concatenating the text representation of multiple elements can be done by appending a comma to the output stream in between calls to this function.
│ │ │
The streamFunction function will be called with the token value as the first parameter and a printf-style format string as the second, with a variable number of further parameters.
Converts the current CBOR type pointed to by value to JSON and writes that to the out stream.
│ │ │
If an error occurs, this function returns an error code similar to CborParsing. The flags parameter indicates one or more of the flags from CborToJsonFlags that control the conversion.
