Kenwood HP 9000 manual Defined by the return value from dlopen. Null is returned, 250

	Shared Library Management Routines
	The dlopen Shared Library Management Routines
		int ident_parm,
		uint64_t load_map_parm);
	Parameters
Parameter			Description
ip_value		An address. The instruction pointer value of the requested library.
desc		A buffer of memory allocated by the user program. The dynamic
		loader fills this in with module information.
desc_size		Size in bytes of the desc buffer.
read_tgm_mem		A pointer to a function used by dlmodinfo to retrieve needed
		information.
		If the value is NULL, the dynamic loader uses its own internal data
		structures to find the correct load module and ignore the
		ident_parm and load_map_parm parameters.
		buffer	A buffer supplied by dlmodinfo to read into.
		ptr	The virtual memory address to read from.
		bufsiz	Tthe size of buffer in bytes.
		ident	The value of the ident_parm parameter to dlmodinfo.
ident_parm		Only used to pass the fourth parameter to read_tgt_mem.
load_map_parm		Only used when calling through read_tgt_mem. Contains the
		starting address of the load map.
	Return Values
	If successful, dlmodinfo returns a handle for the shared library as
	defined by the return value from dlopen(). NULL is returned
	otherwise. The return values are type-converted to unsigned long
	Description
	dlmodinfo is one of a family of routines that give the user direct access
	to the dynamic linking facilities. The dlmodinfo routine retrieves
	information about a load module from a given address value. dlmodinfo
