Considerations
flags input
INT:value
flags.<15>
with a value of 1 indicates that this operation is to be performed nowait. A value
of 0 indicates that this operation is to be performed waited. The default is 0.
flags.<0:14>
must be 0.
scsend-op-num output
INT:ref:EXT:1
returns the server-class send operation number. You can use the server-class send
operation number in place of the file number parameter in calls to CANCEL,
CANCELREQ, and AWAITIOX for nowait sends, and in calls to FILEINFO for
waited and nowait sends, to indicate that the calls refer to server-class send
operations. The value of scsend-op-num is determined on the first successfully
initiated nowait send. This value is returned on every subsequent nowait send that is
initiated successfully. A value of -1 is returned for nowait sends that are not
initiated successfully. A value of -1 is always returned for waited sends.
See Server-Class Send Operation Number
later in this section for more information
about the server-class send operation number.
tag input
INT(32):value
is used for nowait I/O only. The tag is stored by the system and then passed back
to the application by the AWAITIOX procedure when the nowait operation is
completed. You can use the tag parameter to identify multiple nowait I/O
operations. For waited I/O, this parameter is not used and can be omitted. The
default is 0D.
