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

umad_init, umad_done - perform library initialization and finalization

#include <infiniband/umad.h>
int umad_init(void);
int umad_done(void);
    

umad_init() and umad_done() do nothing.

Always 0.

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.
