Functions ¶
func BytesEqual ¶
BytesEqual compares two byte slices for equality.
func CleanString ¶
CleanString converts bytes to a string, trimming null bytes and whitespace.
func ExtractPrintable ¶
ExtractPrintable extracts only printable ASCII characters (0x20-0x7E) from bytes.
func FindBytes ¶
FindBytes searches for needle in haystack and returns the offset, or -1 if not found.
func FindBytesInRange ¶
FindBytesInRange searches for needle in reader between start and end offsets. Returns the absolute offset or -1 if not found.
func ReadBytesAt ¶
ReadBytesAt reads n bytes from r at offset.
func ReadPrintableStringAt ¶
ReadPrintableStringAt reads a string keeping only printable ASCII characters.
func ReadStringAt ¶
ReadStringAt reads a string of n bytes from r at offset, trimming null bytes and spaces.
func ReadUint8At ¶
ReadUint8At reads a single byte from r at offset.
func ReadUint16BEAt ¶
ReadUint16BEAt reads a big-endian uint16 from r at offset.
func ReadUint16LEAt ¶
ReadUint16LEAt reads a little-endian uint16 from r at offset.
func ReadUint32BEAt ¶
ReadUint32BEAt reads a big-endian uint32 from r at offset.
