| # NAME |
| |
| umad_init, umad_done - perform library initialization and finalization |
| |
| # SYNOPSIS |
| |
| ```c |
| #include <infiniband/umad.h> |
| |
| int umad_init(void); |
| |
| int umad_done(void); |
| ``` |
| |
| # DESCRIPTION |
| |
| **umad_init()** and **umad_done()** do nothing. |
| |
| # RETURN VALUE |
| |
| Always 0. |
| |
| # COMPATIBILITY |
| |
| 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. |
