# Encoding to Printable Characters

File module provides functions `HTUU_encode()` and `HTUU_decode()` which convert a buffer of bytes to/from RFC 1113 printable encoding format. This technique is similar to the familiar Unix uuencode format in that it maps 6 binary bits to one ASCII character (or more aptly, 3 binary bytes to 4 ASCII characters). However, RFC 1113 does not use the same mapping to printable characters as uuencode.

This module is implemented by HTUU.c, and it is a part of the W3C Sample Code Library.

    #ifndef HTUU_H
    #define HTUU_H

    extern int HTUU_encode (unsigned char * bufin, unsigned int nbytes,
    			char * bufcoded);

    extern int HTUU_decode (char * bufcoded, unsigned char * bufplain,
    			int outbufsize);

    #endif
