Normally the generated scanner contains references to the unistd.h header file, which is Unix specific. To avoid generating code that includes unistd.h , %option nounistd should be used. Another issue is the call to isatty (a Unix library function), which can be found in the generated code.
Various techniques are used to avoid delimiter collision, or—in other words—to "disguise" bytes of data at the data link layer that might otherwise be incorrectly recognized as the syncword. For example, HDLC uses bit stuffing or "octet stuffing", while other systems use ASCII armor or Consistent Overhead Byte Stuffing (COBS).
Sketch of a V-shaped book scanner from Atiz Sketch of a typical manual book scanner. Commercial book scanners are not like normal scanners; these book scanners are usually a high quality digital camera with light sources on either side of the camera mounted on some sort of frame to provide easy access for a person or machine to flip through the pages of the book.
A rule-based program, performing lexical tokenization, is called tokenizer, [1] or scanner, although scanner is also a term for the first stage of a lexer. A lexer forms the first phase of a compiler frontend in processing. Analysis generally occurs in one pass.
PDF 2.0 defines 256-bit AES encryption as the standard for PDF 2.0 files. The PDF Reference also defines ways that third parties can define their own encryption systems for PDF. PDF files may be digitally signed, to provide secure authentication; complete details on implementing digital signatures in PDF are provided in ISO 32000-2.
4 bytes: an ASCII identifier for this chunk (examples are "fmt " and "data"; note the space in "fmt "). 4 bytes: an unsigned, little-endian 32-bit integer with the length of this chunk (except this field itself and the chunk identifier). variable-sized field: the chunk data itself, of the size given in the previous field.
