 NAME     
 |  |  |  | dec64, enc64, dec32, enc32, dec16, enc16, encodefmt – encoding
    byte arrays as strings 
 | 
 SYNOPSIS     
 |  |  |  | #include <u.h> #include <libc.h> 
    
    
    int    dec64(uchar *out, int lim, char *in, int n) 
    
    
    int    enc64(char *out, int lim, uchar *in, int n) 
    
    
    int    dec32(uchar *out, int lim, char *in, int n) 
    
    
    int    enc32(char *out, int lim, uchar *in, int n) 
    
    
    int    dec16(uchar *out, int lim, char *in, int n) 
    
    
    int    enc16(char *out, int lim, uchar *in, int n) 
    
    
    int    encodefmt(Fmt*)

 DESCRIPTION     
 |  |  |  | Enc16, enc32 and enc64 create null terminated strings. They return
    the size of the encoded string (without the null) or -1 if the
    encoding fails. The encoding fails if lim, the length of the output
    buffer, is too small. 
    
    
    Dec16, dec32 and dec64 return the number of bytes decoded or -1
    if the decoding fails. The decoding fails if the output buffer
    is not large enough or, for base 32, if the input buffer length
    is not a multiple of 8. 
    
    
    Encodefmt can be used with fmtinstall(3) and print(3) to print
    encoded representations of byte arrays. The verbs are H     base 16 (i.e. hexadecimal). The default encoding is in upper
    case. The l flag forces lower case.
 <     base 32
 [     base 64 (same as MIME) 
    
    
    The length of the array is specified as f2. For example, to display
    a 15 byte array as hex:
 
 |  |  |  | char x[15]; fmtinstall('H', encodefmt);
 print("%.*H\n", sizeof x, x);
