nrf_compress_decompress_func_t

typedef int(* nrf_compress_decompress_func_t) (void *inst, const uint8_t *input, size_t input_size, bool last_part, uint32_t *offset, uint8_t **output, size_t *output_size)

#include <include/nrf_compress/implementation.h>

Decompress portion of compressed data. This function will need to be called one or more times with compressed data to decompress it into its natural form.

Parameters

[in]	inst	Implementation specific initialization context. Concrete implementation may cast it to predefined type.
[in]	input	Input data buffer, containing the compressed data.
[in]	input_size	Size of the input data buffer.
[in]	last_part	Last part of compressed data. This should be set to true if this is the final part of the input data.
[out]	offset	Input data offset pointer. This will be updated with the amount of bytes used from the input buffer. If this is not the last decompression call, then the next call to this function should be offset the input data buffer by this amount of bytes.
[out]	output	Output data buffer pointer to pointer. This will be set to the compression's output buffer when decompressed data is available to be used or copied. WARNING: For LZMA implementation, it is only valid if no external dictionary is used. For external dictionary variant (indicated by *inst parameter in init function), this will be set to NULL and user should read from ones own dictionary.
[out]	output_size	Size of data in output data buffer pointer (or in external dictionary). Data should only be read when the value in this pointer is greater than 0.

Return values

0	Success.
-errno	Negative errno code on other failure.
