+zmq_z85_decode \- decode a binary key from Z85 printable text
+.SH "SYNOPSIS"
+.sp
+\fBuint8_t *zmq_z85_decode (uint8_t *dest, char *string);\fR
+.SH "DESCRIPTION"
+.sp
+The \fIzmq_z85_decode()\fR function shall decode \fIstring\fR into \fIdest\fR\&. The length of \fIstring\fR shall be divisible by 5\&. \fIdest\fR must be large enough for the decoded value (0\&.8 x strlen (string))\&.
+.sp
+The encoding shall follow the ZMQ RFC 32 specification\&.
+.SH "RETURN VALUE"
+.sp
+The \fIzmq_z85_decode()\fR function shall return \fIdest\fR if successful, else it shall return NULL\&.
