pydicom.fileutil.find_bytes# pydicom.fileutil.find_bytes(fp: BinaryIO, bytes_to_find: bytes, read_size: int = 128, rewind: bool = True) → int | None[source]# Read in the file until a specific byte sequence found. Parameters: fp (file-like) – The file-like to search. bytes_to_find (bytes) – Contains the bytes to find. Must be in correct endian order already. read_size (int) – Number of bytes to read at a time. rewind (bool) – Flag to rewind file reading position. Returns: found_at – Position where byte sequence was found, else None. Return type: int or None
