Base64 encoding as described in RFC 2045
val encode :
?pos:int ->
?len:int ->
?linelength:int ->
?crlf:bool ->
?plus:char ->
?slash:char ->
string ->
string
Compute the "base 64" encoding of the given string argument. * Note that the result is a string that only contains the characters * a-z, A-Z, 0-9, +, /, =, and optionally spaces, CR and LF characters. * * If pos
and/or len
are passed, only the substring starting at * pos
(default: 0) with length len
(default: rest of the string) * is encoded. * * The result is divided up into lines not longer than linelength
* (without counting the line separator); default: do not divide lines. * If linelength
is smaller than 4, no line division is performed. * If linelength
is not divisible by 4, the produced lines are a * bit shorter than linelength
. * * If crlf
(default: false) the lines are ended by CRLF; otherwise * they are only ended by LF. * (You need the crlf option to produce correct MIME messages.) * * By default, the 63rd character of the alphabet is '+', and the * 64th character is '/'. By passing plus
and slash
you can * choose different characters. *

string ->
string
Decodes the given string argument. * * If pos
and/or len
are passed, only the substring starting at * pos
(default: 0) with length len
(default: rest of the string) * is decoded. * * If accept_spaces
(default: false
) is set, the function ignores * white space contained in the string to decode (otherwise the * function fails if it finds white space). Furthermore, the character * '>' is considered as "space", too (so you don't have trouble with * mbox mailboxes that accidentally quote "From"). * * By default, the 63rd character of the alphabet is '+', and the * 64th character is '/'. By passing plus
and slash
you can * choose different characters.

class encoding_pipe : ?linelength:int -> ?crlf:bool -> ?plus:char -> ?slash:char -> unit ->
Netchannels.pipe
This pipe encodes the data written into the pipe. * linelength
and crlf
work as in encode
.
class decoding_pipe : ?accept_spaces:bool -> ?plus:char -> ?slash:char -> unit -> Netchannels.pipe
This pipe decodes the data written into the pipe. * url_variant
and accept_spaces
work as in decode
.
