(read-sequence seq stream &key (start 0) end) | Function: Destructively modify SEQ by reading elements from STREAM. That part of SEQ bounded by START and END is destructively modified by copying successive elements into it from STREAM. If the end of file for STREAM is reached before copying all elements of the subsequence, then the extra elements near the end of sequence are not updated, and the index of the next element is returned.

(chunga:read-char* stream &optional eof-error-p eof-value) | Function: The streams we're dealing with are all binary with element type (UNSIGNED-BYTE 8) and we're only interested in ISO-8859-1, so we use this to `simulate' READ-CHAR.
|
(chunga:read-token stream) | Function: Read characters from STREAM while they are token constituents (according to RFC 2616). It is assumed that there's a token character at the current position. The token read is returned as a string. Doesn't signal an error (but simply stops reading) if END-OF-FILE is encountered after the first character.
|
(chunga:read-line* stream &optional log-stream) | Function: Reads and assembles characters from the binary stream STREAM until a carriage return is read. Makes sure that the following character is a linefeed. If *ACCEPT-BOGUS-EOLS* is not NIL, then the function will also accept a lone carriage return or linefeed as an acceptable line break. Returns the string of characters read excluding the line break. Returns NIL if input ends before one character was read. Additionally logs this string to LOG-STREAM if it is not NIL.
|
(trivial-gray-streams:stream-read-char stream) | Function: Read one character from the stream. Return either a character object, or the symbol :EOF if the stream is at end-of-file. Every subclass of FUNDAMENTAL-CHARACTER-INPUT-STREAM must define a method for this function.
|
(trivial-gray-streams:stream-read-line stream) | Function: This is used by READ-LINE. A string is returned as the first value. The second value is true if the string was terminated by end-of-file instead of the end of a line. The default method uses repeated calls to STREAM-READ-CHAR.
|
(trivial-gray-streams:stream-read-byte stream) | Function: Used by READ-BYTE; returns either an integer, or the symbol :EOF if the stream is at end-of-file.
|
(read-from-string string &optional (eof-error-p t) eof-value &key (start 0) end preserve-whitespace) | Function: The characters of string are successively given to the lisp reader and the lisp object built by the reader is returned. Macro chars will take effect.
|
Example:(defun base64->obj (string) (ignore-errors (with-safe-io-syntax (read-from-string (base64-decode string))))) | Mentioned in: CLtL2 - 22.2.1. Input from Character Streams CLtL2 - Appendix C. HyperSpec - Function READ-FROM-STRING On Lisp - Operations on Lists PCL - anonymous functions PCL - query parameter types Successful Lisp - chapter21 |
(read-delimited-list endchar &optional (input-stream *standard-input*) recursive-p) | Function: Read Lisp values from INPUT-STREAM until the next character after a value's representation is ENDCHAR, and return the objects as a list.
|
| Mentioned in: CLtL2 - 22.1.5. The Readtable CLtL2 - 22.2.1. Input from Character Streams HyperSpec - Function READ-DELIMITED-LIST Successful Lisp - lesson 12 | |

(ql-allegro:read-vector &rest args) | Undocumented
|
(ql-network:read-octets buffer connection) | Undocumented
|
(chunga:read-http-headers stream &optional log-stream) | Function: Reads HTTP header lines from STREAM (except for the initial status line which is supposed to be read already) and returns a corresponding alist of names and values where the names are keywords and the values are strings. Multiple lines with the same name are combined into one value, the individual values separated by commas. Header lines which are spread across multiple lines are recognized and treated correctly. Additonally logs the header lines to LOG-STREAM if it is not NIL.
|
(read-preserving-whitespace &optional (stream *standard-input*) (eof-error-p t) (eof-value nil) (recursive-p nil)) | Function: Read from STREAM and return the value read, preserving any whitespace that followed the object.
|

|
*read-default-float-format | |
| Mentioned in: HyperSpec - Variable *READ-DEFAULT-FLOAT-FORMAT | |
(chunga:read-name-value-pair stream &key (value-required-p t) cookie-syntax) | Function: Reads a typical (in RFC 2616) name/value or attribute/value combination from STREAM - a token followed by a #\= character and another token or a quoted string. Returns a cons of name and value, both as strings. If VALUE-REQUIRED-P is NIL, the #\= sign and the value are optional. If COOKIE-SYNTAX is true, uses READ-COOKIE-VALUE internally.
|
(ql-clisp:read-byte-sequence &rest args) | Undocumented
|
*read-default-float-format* | Undocumented
|
| Mentioned in: CLtL2 - 2.1.3. Floating-Point Numbers CLtL2 - 22.1.6. What the Print Function Produces CLtL2 - 22.2.1. Input from Character Streams | |
(chunga:read-name-value-pairs stream &key (value-required-p t) cookie-syntax) | Function: Uses READ-NAME-VALUE-PAIR to read and return an alist of name/value pairs from STREAM. It is assumed that the pairs are separated by semicolons and that the first char read (except for whitespace) will be a semicolon. The parameters are used as in READ-NAME-VALUE-PAIR. Stops reading in case of END-OF-FILE (instead of signaling an error).
|
(trivial-gray-streams:stream-read-char-no-hang stream) | Function: This is used to implement READ-CHAR-NO-HANG. It returns either a character, or NIL if no input is currently available, or :EOF if end-of-file is reached. The default method provided by FUNDAMENTAL-CHARACTER-INPUT-STREAM simply calls STREAM-READ-CHAR; this is sufficient for file streams, but interactive streams should define their own method.
|
(alexandria.0.dev:read-file-into-string pathname &key (buffer-size 4096) external-format) | Function: Return the contents of the file denoted by PATHNAME as a fresh string. The EXTERNAL-FORMAT parameter will be passed directly to WITH-OPEN-FILE unless it's NIL, which means the system default.
|
(trivial-gray-streams:stream-read-sequence stream sequence start end &allow-other-keys) | Undocumented
|
(alexandria.0.dev:read-file-into-byte-vector pathname) | Function: Read PATHNAME into a freshly allocated (unsigned-byte 8) vector.
