HP UX 11i v1 I/O Cards Pointer to a buffer into which the Zcom physical, Data is moved into zptt

		ZCOM C I/F Library Routines
		PTFIND (3X)
Threads	This routine may be called from a multi-threaded application using the
Considerations	POSIX (1003.1c) kernel threads API package. This routine has the
	following characteristics when called by a multi-threaded application:
	cancellation point	Thread cancellation can occur when a thread calls this
		routine.
	async-cancel unsafe	The calling thread’s cancelability type must be
		PTHREAD_CANCEL_DEFERRED if cancellation is
		enabled.
	async-signal unsafe	It cannot be called from a signal handler.
	fork unsafe	It cannot be called by a child process after fork(2) but
		before exec(2).
PARAMETERS
	zap	ZCOM address of the terminal. It can be any terminal
		ZLU within the group to be searched. If using method
		1, only its MUX number is used (its port number,
		hence its group, may be different from the target
		terminal).
	zskeyp	ptfind search key. The search key is set up by the
		caller program before this routine is called. It consists
		of a search mode, which indicates the method to be
		used and the data (mode dependent) used in
		searching. If bit ZCOM_PTFIND_NAVL (0x8000) is
		set, ptfind searches the non-available terminals as
		well.
		When using this function in a 32-bit program that is
		running on a 64-bit system, you must be especially
		careful to zero out the zskeyp structure before using
		it. Otherwise, your application may experience
		ZCOM error -84 (ZEBPTR), “User buffer access
		error”.
	zptt (Return Param)	A pointer to a buffer into which the ZCOM physical
		terminal table data will be placed. Note that if the
		physical terminal is not found (i.e., ierr != 0), then no
		data is moved into zptt.
	len	Length in bytes of zptt buffer.
