Function Documentation

static bool handlePossibleHeaderBegin ( const char *  buffer, QIODevice *  dev  )

static

Checks if a token for a central or local header has been found and resets the device to the begin of the token.

If a token for the data descriptor is found it is assumed there is a central or local header token starting right behind the data descriptor, and the device is set accordingly to the begin of that token. To be called when a 'P' has been found.

Parameters

buffer	start of buffer with the 3 bytes behind 'P'
dev	device that is read from

Returns

true if a local or central header begin is or could be reached

Definition at line 295 of file kzip.cpp.

static bool parseExtraField ( const char *  buffer, int  size, bool  islocal, ParseFileInfo &  pfi  )

static

parses the extra field

Parameters

buffer	start of buffer where the extra field is to be found
size	size of the extra field
islocal	true if this is part of a local header, false if of central
pfi	ParseFileInfo object which to write the results into

Returns

true if parsing was successful

Definition at line 243 of file kzip.cpp.

static bool parseExtTimestamp ( const char *  buffer, int  size, bool  islocal, ParseFileInfo &  pfi  )

static

updates the parse information with the given extended timestamp extra field.

Parameters

buffer	start content of buffer known to contain an extended timestamp extra field (without magic & size)
size	size of field content (must not count magic and size entries)
islocal	true if this is a local field, false if central
pfi	ParseFileInfo object to be updated

Returns

true if processing was successful

Definition at line 119 of file kzip.cpp.

static bool parseInfoZipUnixOld ( const char *  buffer, int  size, bool  islocal, ParseFileInfo &  pfi  )

static

updates the parse information with the given Info-ZIP Unix old extra field.

Parameters

buffer	start of content of buffer known to contain an Info-ZIP Unix old extra field (without magic & size)
size	size of field content (must not count magic and size entries)
islocal	true if this is a local field, false if central
pfi	ParseFileInfo object to be updated

Returns

true if processing was successful

Definition at line 179 of file kzip.cpp.

static bool seekToNextHeaderToken ( QIODevice *  dev )

static

Reads the device forwards from the current pos until a token for a central or local header has been found or is to be assumed.

Parameters

dev	device that is read from

Returns

true if a local or central header token could be reached, false on error

Definition at line 329 of file kzip.cpp.
