UMAD_INIT(3)            OpenIB Programmer’s Manual           UMAD_INIT(3)

NAME top

       umad_init, umad_done - perform library initialization and
       finalization

SYNOPSIS top

              #include <infiniband/umad.h>

              int umad_init(void);

              int umad_done(void);

DESCRIPTION top

       umad_init() and umad_done() do nothing.

RETURN VALUE top

       Always 0.

COMPATIBILITY top

       Versions prior to release 18 of the library require umad_init() to
       be called prior to using any other library functions.  Old
       versions could return a failure code of -1 from umad_init().

       For compatibility, applications should continue to call
       umad_init(), and check the return code, prior to calling other
       umad_ functions.  If umad_init() returns an error, then no further
       use of the umad library should be attempted.
