Article contents:[[tags: manual]] [[toc:]] == Module (chicken bytevector) This module contains procedures for dealing with "bytevectors", fixed-size sequences of unsigned 8-bit integers. === bytevector <procedure>(bytevector FIXNUM ...)</procedure> Returns a new bytevector containing the values {{FIXNUM ...}}. === make-bytevector <procedure>(make-bytevector SIZE)</procedure> Returns a bytevector object of {{SIZE}} bytes, aligned on an 8-byte boundary, uninitialized. === bytevector? <procedure>(bytevector? X)</procedure> Returns {{#t}} if {{X}} is a bytevector object, or {{#f}} otherwise. === bytevector-length <procedure>(bytevector-length BYTEVECTOR)</procedure> Returns the number of bytes in {{BYTEVECTOR}}. === bytevector-u8-ref <procedure>(bytevector-u8-ref BYTEVECTOR INDEX)</procedure> Returns the byte at {{INDEX}} in {{BYTEVECTOR}}. === bytevector-u8-set! <procedure>(bytevector-u8-set! BYTEVECTOR INDEX VALUE)</procedure> Destructively modifies the byte at {{INDEX}} in {{BYTEVECTOR}} to {{VALUE}}, which should be a fixnum. === utf8->string <procedure>(utf8->string BYTEVECTOR [VALIDATE])</procedure> Returns a string with the contents of {{BYTEVECTOR}}. if {{VALIDATE}} is given and false, then invalidly encoded characters do not signal an error - byte-sequences that are not representing valid UTF-8 characters are retained and, if extracted with {{string-ref}} are converted to a trailing surrogate pair half in the range U+DC80 to U+DCFF. === string->utf8 <procedure>(string->utf8 STRING)</procedure> Returns a bytevector with the contents of {{STRING}}. === latin1->string <procedure>(latin1->string BYTEVECTOR)</procedure> Returns a string with the contents of {{BYTEVECTOR}} converted from Latin-1 (ISO-8859-1) encoding to UTF-8. === string->latin1 <procedure>(string->latin1 STRING)</procedure> Returns a bytevector with the contents of {{STRING}} encoded as Latin-1 (ISO-?8859-1). === bytevector=? <procedure>(bytevector=? BYTEVECTOR1 BYTEVECTOR2)</procedure> Returns {{#t}} if the two argument bytevectors are of the same size and have the same content. === bytevector-append <procedure>(bytevector-append BYTEVECTOR ...)</procedure> Returns a new bytevector holding the concatenated contents of all argument bytevectors. === bytevector-copy <procedure>(bytevector-copy BYTEVECTOR #!optional START END)</procedure> Returns a new bytevector holding the contents of {{BYTEVECTOR}} between the indices {{START}} to {{END}}. === bytevector-copy! <procedure>(bytevector-copy! TO AT FROM #!optional START END)</procedure> Copioes the contents of the bytevector FROM between the indices {{START}} to {{END}} into the bytevector {{TO}}, starting at index {{AT}}. --- Previous: [[Module (chicken bitwise)]] Next: [[Module (chicken condition)]] Description of your changes:
