Detailed Description

Wrapper for the inflate algorithm.

Initialize/free algorithm resources. Provide successive arrays of compressed bytes via the input() method. Compute successive arrays of uncompressed bytes via the inflate() method.

Member Function Documentation

inflate()

int4 ghidra::Decompress::inflate	(	uint1 *	buffer,
		int4	sz
	)

Inflate as much as possible into given buffer.

Return the number of bytes of output space still available. Output may be limited by the amount of space in the output buffer or the amount of data available in the current input buffer.

Parameters

buffer	is where uncompressed bytes are stored
sz	is the size, in bytes, of the buffer

Returns

the number of output bytes still available

input()

void ghidra::Decompress::input ( uint1 *  buffer, int4  sz  )

inline

Provide the next sequence of compressed bytes.

Parameters

buffer	is a pointer to the compressed bytes
sz	is the number of bytes
