Member Function Documentation

u32 CFileUnpacker::GetVersion ( ) const

inline

Returns

version number that was stored in the file's header.

Definition at line 115 of file FileIo.h.

void CFileUnpacker::Read	(	const VfsPath &	filename,
		const char	magic[4]
	)

open and read in given file, check magic bits against those given; throw variety of exceptions if open failed / version incorrect, etc.

Definition at line 111 of file FileIo.cpp.

void CFileUnpacker::UnpackRaw	(	void *	rawData,
		size_t	rawDataSize
	)

unpack given number of bytes from the input into the given array.

throws PSERROR_File_UnexpectedEOF if the end of the data stream is reached before the given number of bytes have been read.

Definition at line 150 of file FileIo.cpp.

size_t CFileUnpacker::UnpackSize

(

)

use UnpackRaw to retrieve 32-bits; returns their value as size_t after converting from little endian to native byte order.

Definition at line 162 of file FileIo.cpp.

void CFileUnpacker::UnpackString

(

CStr8 &

result

)

unpack a string from the raw data stream.

Parameters

result

is assigned a newly constructed CStr8 holding the string read from the input stream.
