NAME

       scan_uuencoded - decode uuencoded data

SYNTAX

       #include <libowfat/textcode.h>

       size_t scan_uuencoded(const char *src,char *dest,size_t* destlen);

DESCRIPTION

       scan_uuencoded decodes uuencoded data from src into dest.  It will stop when it encounters
       any non-valid input characters.  It will then write the number of decoded  bytes  in  dest
       into *destlen, and return the number of bytes decoded from src.

       Note  that  real  world  uuencoded  data  is  sometimes  permitted  to  contain whitespace
       characters or new lines. This function will not allow those and return  the  decoded  data
       until then.

       uudecoding works on lines, and the first byte in each line contains the length of the line
       (encoded). scan_uuencoded expects one such line as input, and it will decode all the bytes
       in it.

       uuencoded  data  can  contain bytes from 0x21 to 0x96, which means it is not "string safe"
       (can contain single and double quotes and backslash).

       dest can be NULL. destlen can be NULL. dest can be src.

RETURN VALUE

       scan_uuencoded returns the number of bytes successfully scanned and processed from src.

EXAMPLES

       scan_uuencoded("&9FYO<F0*",buf,&i) -> return 9, i=5, buf="fnord"
