.SH NAME
.PP
umad_init, umad_done - perform library initialization and finalization
.SH SYNOPSIS
.IP
.nf
\f[C]
#include <infiniband/umad.h>

int umad_init(void);

int umad_done(void);
\f[R]
.fi
.SH DESCRIPTION
.PP
\f[B]umad_init()\f[R] and \f[B]umad_done()\f[R] do nothing.
.SH RETURN VALUE
.PP
Always 0.
.SH COMPATIBILITY
.PP
Versions prior to release 18 of the library require
\f[B]umad_init()\f[R] to be called prior to using any other library
functions.
Old versions could return a failure code of -1 from
\f[B]umad_init()\f[R].
.PP
For compatibility, applications should continue to call
\f[B]umad_init()\f[R], and check the return code, prior to calling other
\f[B]umad_\f[R] functions.
If \f[B]umad_init()\f[R] returns an error, then no further use of the
umad library should be attempted.
