.SH "NAME"
radcli_avp_get_uint64 \- Read an attribute's value as a 64-bit integer or ifid.
.SH SYNOPSIS
.nf
.B #include <radcli/>
.sp
\fBint radcli_avp_get_uint64\fP(
    \fBconst radcli_avp  *\fP\fIa\fP,
    \fBuint64_t          *\fP\fIout\fP
);
.fi
.SH DESCRIPTION
.SH PARAMETERS
.TP
.B a
the attribute; radcli_avp_def(a) must be RADCLI_TYPE_INTEGER64 or RADCLI_TYPE_IFID  see radcli_avp_add_uint64() for why the two types share this getter. 

.TP
.B out
where to write the value (a big-endian uint64_t for RADCLI_TYPE_IFID); may be NULL to just check validity. 

.SH RETURN VALUE
.PP
0 on success, -1 if a's type is neither.
