Programmer-Level Compatibility
System Call Compatibility
The CommKit software supports the open, close, read, poll, and write
system calls. With these two exceptions, the current software interfaces are
STREAMS interfaces. The TTY ioctl directives are supported by the
standard HP-UX STREAMS module ldterm. Any low-level support that
ldterm requires is supplied by the current STREAMS module dkty.
dksplice(3X) dksplice()
Splices two existing circuits using the supplied file descriptors.
Note: If you specify standard input as an argument to dksplice()
and if the function call fails, you must re-initialize standard input.
See the dksplice example later in this chapter.
dksplwait(3X) dksplwait()
Waits for an existing circuit to be spliced. Provides a timeout value
so that a process may choose not to wait indefinitely.
dktsplice(3X) dktr_splice()
Requests a transparent splice of an incoming call to the specified
address within the specified channel range.
dktsplice(3X) dktr_osplice()
Requests a transparent splice of an incoming call to the specified
address within the specified channel range.
dktsplice(3X) dktr_call()
Makes a call for transparent splice purposes setting the baud rate
and URP parameters correctly for the spliced endpoints.
dkurpctl(3X) dkset_no_ainit()
Sets the URP parameters to withhold acknowledgments of URP
initialization requests.
dkurpctl(3X) dkset_one_ainit()
Sets the URP parameters to respond to only one URP initialization
request.
maphost(3X) maphost()
Maps partial dialstring information into a complete dialstring by
searching the dkhosts table. Unchanged from previous releases.
maphost(3X) miscfield() Provides miscellaneous information from the dkhosts table.
Unchanged from previous releases.
