       These  functions	retrieve information on	a type definition (SMIng) or a
       simple ASN.1 type definition (SMIv1/v2) or a TEXTUAL-CONVENTION defini-
       tion (SMIv2). Base types	may also be retrieved by these functions.

       The  smiGetType() function retrieves a struct SmiType that represents a
       type. Type may be either	a fully	qualified descriptor or	a simple  type
       name.   If  smiModulePtr	is not NULL it used to limit the search	to the
       given module. If	the type is not	found, smiGetType() returns NULL.

       The smiGetFirstType() and smiGetNextType() functions are	used to	itera-
       tively  retrieve	 struct	 SmiTypes. smiGetFirstType() returns the first
       one defined in the module specified by smiModulePtr.  Subsequent	 calls
       to  smiGetNextType()  return  the following ones.  If there are no more
       type definitions	in the module NULL is returned.

       The smiGetParentType() function retrieves a struct SmiType of the  type
       from  which the type specified by smiTypePtr is derived.	If there is no
       parent type (i.e. the type specified by smiTypePtr  is  a  base	type),
       smiGetParentType() returns NULL.

       Similarly,  the	smiGetFirstRange() and smiGetNextRange() functions are
       used to iteratively retrieve struct SmiRanges that represent range  re-
       strictions  of  the type	specified by smiTypePtr, either	size ranges of
       an octet	string type or value ranges in case of a numeric type.

       Similarly,  the	smiGetFirstNamedNumber()  and  smiGetNextNamedNumber()
       functions  are used to iteratively retrieve struct SmiNamedNumbers that
       represent named numbers of the type specified by	smiTypePtr, which  has
       to be either a bit set or an enumeration	type.

       The  smiGetTypeModule()	function  returns  the module that defines the
       type given by struct SmiTypePtr.

       The smiGetTypeLine() function returns the line number within the	module
       where the type specified	by smiTypePtr is defined.
