Function Documentation

wscbor_enc_array_head()

void wscbor_enc_array_head	(	GByteArray *	buf,
		size_t	len
	)

Add an array header with a definite length.

Note

The items which follow this header must agree with the definite length.

Parameters

[in,out]	buf	The buffer to append to.
	len	The number of items of the array.

wscbor_enc_boolean()

void wscbor_enc_boolean	(	GByteArray *	buf,
		bool	value
	)

Add an item containing a bool value.

Parameters

[in,out]	buf	The buffer to append to.
	value	The value to write.

wscbor_enc_bstr()

void wscbor_enc_bstr	(	GByteArray *	buf,
		const uint8_t *	ptr,
		size_t	len
	)

Add an item containing a definite length byte string.

Parameters

[in,out]	buf	The buffer to append to.
[in]	ptr	The data to write.
	len	The length of the data to write. This MUST be no longer than the actual size of data.

wscbor_enc_bstr_bytearray()

void wscbor_enc_bstr_bytearray	(	GByteArray *	buf,
		GByteArray *	src
	)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. This is a shortcut to adding a byte string stolen from an existing array. This can be useful to embed encoded CBOR into a byte string (see CDDL operators ".cbor" and ".cborseq" from Section 3.8.4 of RFC 8610).

Parameters

[in,out]	buf	The buffer to append to.
[in,out]	src	The buffer to steal from.

wscbor_enc_int64()

void wscbor_enc_int64	(	GByteArray *	buf,
		int64_t	value
	)

Add an item containing an unsigned or negative int.

Parameters

[in,out]	buf	The buffer to append to.
	value	The value to write.

wscbor_enc_map_head()

void wscbor_enc_map_head	(	GByteArray *	buf,
		size_t	len
	)

Add a map header with a definite length.

Note

The items which follow this header must agree with the definite length.

Parameters

[in,out]	buf	The buffer to append to.
	len	The number of pairs in the map.

wscbor_enc_null()

void wscbor_enc_null

(

GByteArray *

buf

)

Add an item containing a null value.

Parameters

[in,out]

buf

The buffer to append to.

wscbor_enc_tstr()

void wscbor_enc_tstr	(	GByteArray *	buf,
		const char *	ptr
	)

Add an item containing a definite length text string.

Parameters

[in,out]	buf	The buffer to append to.
[in]	ptr	The null-terminated text to write.

wscbor_enc_uint64()

void wscbor_enc_uint64	(	GByteArray *	buf,
		uint64_t	value
	)

Add an item containing an unsigned int.

Parameters

[in,out]	buf	The buffer to append to.
	value	The value to write.

wscbor_enc_undefined()

void wscbor_enc_undefined

(

GByteArray *

buf

)

Add an item containing an undefined value.

Parameters

[in,out]

buf

The buffer to append to.
