Detailed Description

Implementation of flat-buffer sequential access.

Function Documentation

BSL_SeqReader_Destroy()

void BSL_SeqReader_Destroy

(

BSL_SeqReader_t *

obj

)

Release resources from a sequential reader.

This also frees memory of the instance itself.

Parameters

[in,out]

obj

The reader handle.

BSL_SeqReader_Get()

int BSL_SeqReader_Get	(	BSL_SeqReader_t *	obj,
		uint8_t *	buf,
		size_t *	bufsize
	)

Iterate a sequential reader.

Parameters

[in,out]	obj	The reader handle.
[out]	buf	The output buffer to fill.
[in,out]	bufsize	The available output buffer size as input, set to the used buffer size as output.

Returns

Zero if successful.

BSL_SeqWriter_Destroy()

void BSL_SeqWriter_Destroy	(	BSL_SeqWriter_t *	obj,
		bool	success
	)

Release resources from a sequential writer and possibly commit the writes.

This also frees memory of the instance itself.

Parameters

[in,out]	obj	The writer handle.
	success	Set true if all of the writing succeeded.

BSL_SeqWriter_Put()

int BSL_SeqWriter_Put	(	BSL_SeqWriter_t *	obj,
		const uint8_t *	buf,
		size_t	bufsize
	)

Iterate a sequential writer.

Parameters

	obj	The writer handle.
[in]	buf	The input buffer to copy from.
[in,out]	bufsize	The available input buffer size as input, set to the used buffer size as output.

Returns

Zero if successful.
