.TH ENCODE 2.SH NAMEdec64, enc64, dec32, enc32, dec16, enc16, encodefmt \- encoding byte arrays as strings.SH SYNOPSIS.B #include <u.h>.br.B #include <libc.h>.PP.Bint	dec64(uchar *out, int lim, char *in, int n).PP.Bint	enc64(char *out, int lim, uchar *in, int n).PP.Bint	dec32(uchar *out, int lim, char *in, int n).PP.Bint	enc32(char *out, int lim, uchar *in, int n).PP.Bint	dec16(uchar *out, int lim, char *in, int n).PP.Bint	enc16(char *out, int lim, uchar *in, int n).PP.Bint	encodefmt(Fmt*).SH DESCRIPTION.PP.IR Enc16 ,.I enc32and.I enc64create null terminated strings.  They return the size of theencoded string (without the null) or -1 if the encoding fails.The encoding fails if.IR lim ,the length of the output buffer, is too small..PP.IR Dec16 ,.I dec32and.I dec64return 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 multipleof 8..PP.I Encodefmtcan be used with.IR fmtinstall (2)and.IR print (2)to print encoded representations of byte arrays.The verbs are.TP.B Hbase 16 (i.e. hexadecimal).TP.B <base 32.TP.B [base 64 (same as MIME).PD.PPThe length of the array is specified as.IR f2 .For example, to display a 15 byte array as hex:.EX     char x[15];     fmtinstall('H', encodefmt);    print("%.*H\\n", sizeof x, x); .EE.SH SOURCE.B /sys/src/libc/port/u32.c.br.B /sys/src/libc/port/u64.c
