.SH "NAME"
zmq_z85_decode \- decode a binary key from Z85 printable text
.SH "SYNOPSIS"
.sp
\fBuint8_t *zmq_z85_decode (uint8_t *dest, const 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\&.
