.SH NAME
libaxl_get_decnet_object - Get DECnet object name for a display
.B (ADVANCED)
.SH SYNOPSIS
.nf
#include <libaxl.h>
#define LIBAXL_DECNET_OBJECT_MAX /* value omitted */
int libaxl_get_decnet_object(char *\fIbuf\fP, size_t \fIsize\fP, int *\fIdisplay\fP);
.fi
.SH DESCRIPTION
The
.BR libaxl_get_decnet_object ()
function stores, in the buffer specified
in the
.I buf
parameter, the DECnet object name used
for the display specified in the

.PP
The value of the
.I size

.I size
must be 0.
.SH RETURN VALUE
The

function returns the number of bytes
the DECnet object name consists of

used in C strings, which is also written
to the buffer if it fits), or -1 on
failure.
.SH ERRORS
The
.BR libaxl_get_decnet_object ()
function may fail if
.TP
.I EOVERFLOW
The value of the
.I size
argument is greater than {INT_MAX}.
