structure_get_description

	status.i4.v = structure_get_description(name.i1a.r, description.i1a.r
						[,long_descr.i1a.r])

	This routine retrieves the description of a named structure.
	A value of NULL can be passed for any returned argument that
	is not needed.

	name		null terminated structure name
			(Note: The name format is [{class}.]{struct}.)
	description	returned null terminated structure description
			(allow STRUCT_DESCRIPTION_LEN + 1 characters)
	[long_descr]	returned null terminated long structure description
			(allow STRUCT_LONG_DESCRIPTION_LEN + 1 characters)
			(default is NULL)

	This function returns status values as follows:

	OK			success
	CLIB_NO_SUCH		structure name was not found
	CLIB_AMBIGUOUS		ambiguous name (must specify class name)
	SQL_xxx			error retrieving structure description

	This function requires the following include files:

	cbslib_h, generic_structures_h, acnet_errors_h
