These functions retrieve information on a type definition (SMIng) or a simple ASN.1 type definition (SMIv1/v2) or a TEXTUAL-CONVENTION definition (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 iteratively 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 restrictions 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.
