| * |
| * Functionality: |
| * To explore any of the IUCV functions, one must first register |
| * their program using iucv_register_program(). Once your program has |
| * successfully completed a register, it can exploit the other functions. |
| * For furthur reference on all IUCV functionality, refer to the |
| * CP Programming Services book, also available on the web |
| * thru www.ibm.com/s390/vm/pubs, manual # SC24-5760 |
| * |
| * Definition of Return Codes |
| * -All positive return codes including zero are reflected back |
| * from CP except for iucv_register_program. The definition of each |
| * return code can be found in CP Programming Services book. |
| * Also available on the web thru www.ibm.com/s390/vm/pubs, manual # SC24-5760 |
| * - Return Code of: |
| * (-EINVAL) Invalid value |
| * (-ENOMEM) storage allocation failed |
| * pgmask defined in iucv_register_program will be set depending on input |
| * paramters. |
