|
|
|
|
*
|
|
|
|
|
* 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.
